HEIDI Klum has posted a new video showing off her youngest child on his birthday.
The 50-year-old America's Got Talent judge shared the video on her Instagram feed.
Heidi's son Johan Riley Fyodor Taiwo Samuel turned 17 on Wednesday, November 22.
Johan is rarely seen on social media or in public now that he's a teenager, and his mom's birthday post was no exception.
The video the model posted was a major throwback to when her baby boy was still practically a baby.
He appeared to be about six or seven years old in the clip where he was rocking out at a concert.

Heidi shares four children Leni, 19, Henry, 18, Johan, 16, and Lou, 14, with her ex-husband, Seal, 60.

LOOK-ALIKE DAUGHTER
Heidi's fans did a double take after she shared a throwback photo where she looked just like her daughter Leni.
She recently took to Instagram to post her modeling headshot from her teenage years.
It showed her looking sultrily at the camera with her natural brunette hair flowing in loose waves and a dark red lip.
The runway superstar said in her caption that she was the same age in the photo as her daughter, Leni, is now.
Fans couldn't help but point out the crazy resemblance between the mother-daughter duo and said so in the comments.
"They look 100% alike," one person said.
"She looks so much like you at that age," a second agreed.
"Wow you two look alike," another echoed.
SEXY MOMMA
Most recently, Heidi showed off her incredible figure while wearing a skimpy outfit at the F1 Grand Prix in Las Vegas.
She went braless under a leather shirt as she attended the event with her husband Tom Kaulitz, 34.
She wore her black shirt with a pair of black high-waisted pants, and fishnet tights while accessorizing with black thigh-high boots and a black leather chain trim bag.
Heidi shared a cheeky elevator selfie with Tokio Hotel guitarist Tom, who was wearing a chunky navy sweater and black pants.
