Christian first met the Spice Girl at the Monaco Grand Prix in 2009.

'Geri] was a guest of [former CEO of the Formula One Group] Bernie Ecclestone's in Monaco one year and came down the pit lane,” he explained. “I remember [McLaren boss] Ron Dennis was standing next to me and Eddie Jordan was there as well,' he previously told The Telegraph.

She gave Ron a kiss on the cheek, and she gave Eddie a kiss on the cheek. So I thought, "OK, I'm on for a kiss on the cheek here!" And I went to give her one and she shoved her hand out at me. 

Christian and Geri's relationship came under fire after the Formula One boss left his long-term partner Beverley Allen six months after the birth of their daughter, Olivia.

The pair are said to have briefly split while he attempted to rescue his 14-year relationship with Beverley.

Beverley had been by his side throughout his astonishing ascent while he acted as a stepfather to her two sons from a previous relationship, Kieron and Liam.

Engagement

Ginger Spice and Christian announced their engagement in 2014 with an advertisement in The Times, nine months after they began dating. 

'The engagement is announced between Christian, son of Mr and Mrs G.M. Horner and Geraldine, daughter of the late Mr L.F. Halliwell and Mrs A Parkinson.'

Afterwards Geri wrote on X, formerly Twitter: 'Christian and I are delighted to announce that we are engaged! We're both very happy'

Geri and Christian married at St Mary's church in Woburn, Bedfordshire in 2015. 

The Spice Girl chose British designer Phillipa Lepley for her A-line lace bridal gown. 

The couple were joined by her then nine-year-old daughter, Bluebell, whose father is screenwriter Sacha Gervasi.

Guests included Geri's former Spice Girls co-star Emma Bunton, radio presenter and singer Myleene Klass, and TV presenter Amanda Holden. 

Christian's parents were reportedly left devastated when the sporting professional left his partner of 14 years, Beverley Allen, to be with the chart-topping star and therefore chose not to see the duo tie the knot. 

Children and family life

She went on to marry Formula 1 team principal, Christian Horner in 2015. They have a son together named Monty, six. Christian also has daughter Olivia, nine, from his relationship with ex Beverley. 

Geri admitted that she now finds 'compromising a challenge' when raising Monty with her 'loving' husband Christian due to her past experience.

Joining Giovanna Fletcher on her Happy Mum Happy Baby podcast, the Spice Girl drew on her 'very different set-ups' of raising both her children.

She explained while she needed 'broad shoulders' to raise Bluebell as a single parent, she later struggled when 'learning how to be a team.'

Geri told Giovanna: 'I've experienced both and I can tell you that, yeah I had my mom to help me with Blue. So I'm very grateful. And her granddad is gorgeous so it was a fantastic role model for her.

'He takes her to football, which is amazing and I think you know, they both have their blessings and challenges.

'Being a single parent, mother you don't have to answer to anyone, but it's all on you. And that can be quite stressful and you have to be responsible. All the responsibilities are on you in every way.

'Broad shoulders are needed and sometimes it's lonely. So I've experienced that. And then, you know, having the blessing of having a lovely husband or partner, which I've experienced. That's amazing.

'So it's not all on you, but then you've got to compromise, we might have, you know, we're all different in the way we think things should be done. So learning to be a team, which has been a challenge for me.'

Allegations

Christian is fighting for his job as Red Bull team principal after the Formula One team launched an investigation into allegations of 'inappropriate behaviour'.

MailOnline understands the accusations surrounding relate to claims of wrongdoing made by a team employee. 

Accusations relating to Christian were flying around within the sport over the weekend, ahead of the new season starting next month. 

But they are flatly denied by the father-of-two and no evidence of that nature has been established.

Christian described the accusations as 'nuts' in a message protesting his innocence to MailOnline. 

A source within the Red Bull team added that the claims under scrutiny related to 'incredibly controlling behaviour'. Chrisian said: 'I completely deny these claims.'

A statement from Red Bull Austria, the team's parent company, said: 'After becoming aware of recent allegations, the company initiated an independent investigation. 

'This investigation, which is already underway, is being carried out by an external specialised lawyer. The company takes these matters extremely seriously and the investigation will be complete as soon as practicable. It would not be appropriate to make any further comments at this time.'

Confirmation of the investigation follows 36 hours of denials from the factory in Milton Keynes of any alleged wrongdoing.
