Machine Gun Kelly had fans buzzing after sharing a cryptic message just two days following his shocking split with his pregnant girlfriend Megan Fox.

The 34-year-old rocker took to Instagram Stories on Thursday to post a snippet of his performance of Last Christmas from NBC’s A Motown Christmas special, accompanied by a bandaged heart emoji.

He captioned the clip with a brief but telling message: 'Give it to someone special.'

The video featured MGK singing the iconic George Michael holiday song, which includes the poignant lyrics: 'Last Christmas, I gave you my heart, but the very next day you gave it away. This year, to save me from tears, I'll give it to someone special.'

The timing of the post comes on the heels of Megan’s ex-husband Brian Austin Green weighing in on the couple's breakup

The 51-year-old Beverly Hills, 90210 star didn't mince words when discussing the situation, calling MGK, whose real name is Colson Baker, 'immature.'

Surprisingly, Brian — who was spotted out earlier on Thursday — claimed to have not even heard that his ex-wife Megan, 38, had broken up with MGK, 34, just weeks after they announced they were expecting their first child together

When the interviewer mentioned reports that Megan alleged broke up with MGK after finding text messages with other women on his phone, the TV star let out a long, theatrical sigh and threw his head back while rolling his eyes.

After getting caught up to speed on the latest reports, Brian's first thought was MGK's age.

'How old is he? He's in his 30s, isn't he?' he asked the interviewer. 

Brian claimed to have 'no idea' when asked if the musician had had 'a lot' in infidelities while dating his former fiancée, but he thought MGK was too old for that kind of alleged behavior.

'But in your 30s? Like, I don't know, grow up,' he continued, noting that his ex-wife was pregnant with that pop-punk rockers child.

Brian went on to clarify that he just wants 'the best' for both Megan and her future child, as well as the three children they already share: sons Noah, 12; Bodhi, 10; and Journey, eight.

'That's a shame,' he said of the situation after a pause. 'I'm heartbroken about it because I know she's been so excited and the kids are so excited for life and the change and all of that.'

But when he was asked if Machine Gun Kelly potentially no longer being around his children, he emphatically stated that nothing about his ex's breakup made him 'feel any better.' 

'If that's the case — and I don't know the facts of it — but if that's the case it's a tragic situation, and I wouldn't wish that on anybody,' Brian added compassionately.

But he played it coy when asked if he hoped Megan and MGK would stay separated, instead saying he hoped for 'the best outcome' for Megan and for their kids, whatever that might be.

Brian and Megan began dating in 2004, when he was 30 and she was just 18. 

The couple got engaged two years later, but then ended their engagement in 2009, only to get engaged again in June 2010. It was only days later that they tied the knot in Hawaii. 

However, the marriage was rocky, and they announced a split in 2015. Megan filed for divorce shortly afterward, only for them to reconcile in 2016, though she waited until 2019 to formally dismiss her divorce petition. 

But then the marriage came to an end in 2020 when they split for good, and their divorce was finalized by the following year. 

Since his split from Megan, Brian has been dating the Australian professional dancer Sharna Burgess since late 2020. The couple went on to welcome a son Zane, now two, in June of 2022. 

Brian also has an older son, 22-year-old Kassius, from his relationship and engagement with his Beverly Hills, 90210 costar Vanessa Marcil. The two ended their engagement and split in 2003, a year after kassius was born 

His interview happened a day after reports emerged that Megan's friends 'want her to end her romance with Machine Gun Kelly for good,' following their shock split weeks after her pregnancy reveal.

Fox and MGK ended their near five year romance over Thanksgiving weekend while together in Vail, Colorado — with the actress around six months pregnant with their first child together.

Fox's inner circle are said to be concerned MGK is a 'toxic influence' on her well-being with sources telling TMZ her friends have advised her to 'move on once and for all.' 

Sources claimed Fox's distress is 'deepened' by a 'continuous cycle of breaking up and reconciling' but that the star 'feels like he needs her.'

Another source added: 'She has a history of taking him back, even when things don't get better. She deserves better than this.'

The pair are said to have split less than two weeks after the pregnancy reveal after Fox 'found material on MGK’s phone that was upsetting, and it made her want him to leave the trip early' per TMZ.

The musician then left the trip early and the exes have not seen each other since. 

DailyMail.com previously contacted representatives for the pair for comment.

An insider revealed that actress allegedly 'found text messages involving other women and decided she was done.'

'When they went away for the Thanksgiving holiday, she became suspicious and decided to go through his phone,' a source told Page Six.

Before making her discovery, the Jennifer’s Body star already 'had trust issues' with My Ex’s Best Friend hitmaker 'because of past behavior.' 

The insider noted that despite their ups and downs over the years, she 'was willing to look past all that' and 'rebuild her trust with Colson and was excited to grow their family together.'

It was accompanied by a picture of a positive pregnancy test. 'Nothing is ever really lost. welcome back ❤️' she wrote announcing the good news. 

The announcement was soundtracked to the MGK song Last November, which refers to the miscarriage she previously suffered with the musician. 

MGk commented for the first time on her  pregnancy news after her stunning  outing in a sheer dress.

He wrote: 'isolating myself in the desert next week to restart this album from scratch.

'when inspiration flows through me unblocked, we will reach the destination in no time.

'don’t worry. after all, im about to be a dad again!'

Fox previously opened up about her miscarriage in her 2023 book of poetry, Pretty Boys Are Poisonous.

Megan wrote about an ultrasound of a baby girl at 10 weeks and a day, per excerpts from People, and said: 'maybe if you hadn't... maybe if i had...

She continued, 'I want to hold your hand / hear your laugh, but now / I have to say / goodbye,' and later adds, 'I close my eyes and imagine holding you tight against my chest as they rip you from my insides'.

Elsewhere in the book, she wrote, 'I will pay any price. Tell me please / what is the ransom / for her soul?'

During an interview on Good Morning America at the time, Megan said she had 'never been through anything like that before in my life'.

'It was very difficult for both of us,' she explained. 'And it sent us on a very wild journey together and separately, and together and apart, and together and apart, and together and apart, trying to navigate, "What does this mean? Why did this happen?'"

Megan and MGK had never discussed the pregnancy loss prior to the poetry book, however the 'Bloody Valentine' hitmaker did appear to allude to it at the Billboard Music Awards in May 2022, dedicating his performance to Megan and adding, 'This is for our unborn child.' 

Megan also suffered an ectopic pregnancy years earlier.

In an interview with Good Morning America, Fox explained how the pregnancy loss had affected their relationship.

'I had never been through anything like that before in my life,' she explained. 

'I have three kids, so it was very difficult for both of us, and it sent us on a very wild journey together and separately and together and apart … trying to navigate, "What does this mean?" and "Why did this happen?"'

MGK, whose legal name is Colson Baker, is dad to 15-year-old Casie, whom he shares with his ex Emma Cannon. 

The couple have been together since 2020 and got engaged two years later, but have yet to tie the knot. 

Their due date is in March.

Megan and MGK have had a passionate and rocky relationship.

They first met  on the set of Midnight in The Switchgrass before getting engaged in 2022. 

When announcing their betrothal on Instagram, Megan said she and MGK 'drank each other's blood' to celebrate the occasion.

But just over a year later, Megan sensationally hinted she had split from MGK as she shared a cryptic Instagram post before completely deleting her account.

The actress posted a video in which she appeared to burn a letter in a bonfire, along with a bag.

She also uploaded a very raunchy string of mirror selfies while joined by a male pal, in which she put on a busty display in a plunging black top and cut-out trousers.

Megan wrote in her caption, 'You can taste the dishonesty/ it’s all over your breath,' which are lyrics from Beyoncé's 2016 track, Pray You Catch Me, about her husband Jay Z's own affair.

She then removed all traces of Machine Gun Kelly from her Instagram grid, having unfollowed him before deleting her account altogether.

Ultimately they seemed to patch things up and things appear to be all well between them now, with the couple being seen together ever since.

The rapper also recently tattooed his entire upper body in black ink, reportedly to prove to Megan that he is 100% committed to their relationship.

In March, during an appearance on Alex Cooper's Call Her Daddy podcast, Megan revealed she and MGK had ended their engagement at some point.

'I feel like everyone has such an opinion on your guys relationship. You got engaged, then I think it was called off, then we don't know what's going on with you. How would you describe your relationship with MGK?' host Alex Cooper asked.

Megan responded: 'I think that what I've learned from being in this relationship is that it's not for public consumption, so I think as of now, I don't have a comment on like the status of the relationship per say.

'What I can say is that is what I refer to as being my twin soul and there will always be a tether to him no matter what. I can't say for sure what the capacity will be, but I will always be connected to him somehow.

'Beyond that I'm not willing to explain. But all those things you said were accurate things that have occurred and I can see them being confusing or interesting to people and them being like, "What's up?"'

Her final comment confirmed speculation she had ended her engagement from Kelly.

Megan was previously married to Green from 2010 to 2021. They welcomed three children together during their marriage before their union officially ended. 

Brian has been with DWTS professional Sharna Burgess since 2020 and they have son Zane Walker Green, two, together.
