The motocross star shared pictures of his son post-tumble.
Pink and Carey Hart's son, Jameson, is taking his first steps.
The couple's adorable little boy, who turns 1 on Dec, 26, is learning how to walk, and with that comes some expected falls and tumbles. On Friday, the motocross star shared a picture of his baby smiling with a red upper lip.
"Lil man just started walking and took a good slam yesterday. Bloody nose and all! Even has the war wound to prove it. #1stOfMany #RunsInTheFamily," Hart captioned the pic.
He then posted a second snap of his tough little boy with his battle scar.
Last month, Pink stepped out with her adorable 6-year-old daughter, Willow, in matching princess-like gowns. Back in August, the singer, Hart and Willow all sported three-piece suits at the MTV Video Music Awards -- little Jameson stayed home that night.
ET caught up with Pink in October, where she opened up about struggling to balance her career and her life at home as a mom to two kids.
"I would love to get rid of some of the mom guilt 'cause that really shades a lot of my decision making," she revealed. "I walk out the door, I leave my heart behind and it is conflicting, it is always conflicting and I want to be the best mom in the world."
