Pink's daughter Willow, whom she shares with husband Carey Hart, has caught the musical theater bug, Hart says.

In an Instagram post on Sunday, the former professional motocross racer boasted about his 11-year-old daughter's musical talents.

"I'm so proud of the lil woman that Willow is becoming!!! She has been bitten by the theater bug, and she is killing it!!!" he wrote alongside a carousel of photos of Willow on stage.

In the first two photos, Willow is pictured dancing alongside her fellow performers. The third and final photo captured an adorable moment of the father-daughter duo sharing a cuddle at a show.

Hart, 47, said Willow has done "two different productions this summer," performing in both "High School Musical" and "Grease."

"It seriously rattled me ... seeing her on the stage and how she is getting older," Hart wrote. "I love you munch[k]in, and so proud of you."

This isn't the first time Willow has shown an interest in performing. She was featured in Pink's song "Cover Me in Sunshine" last year, also appearing in the music video. The two also performed together on stage at the 2021 Billboard Music Awards.

Hart and Pink, 42, are also parents to 5-year-old son Jameson.
