Michael Douglas is simply in awe of his son's musical talent.

The Ant-Man actor, 78, appeared to be beaming with pride in a new Instagram video, which depicted his 22-year-old son Dylan Michael Douglas jamming out on the piano in the background.

The clip, shared to Michael's Instagram page on Tuesday, May 9, featured the Oscar-winning film star lounging out on a chair as he happily listened to his son belting out in song while playing the keys.

"So proud of my boy," Michael told the camera, as a giant smile broke out across his face.

The Fatal Attraction star shared the same sentiment in the post's caption, which read, "So proud of my boy! 🎤 🎹 @dylan__douglas."

Dylan is one of Michael's three children, two of whom he shares with wife Catherine Zeta-Jones. The longtime pair, who have been married since 2000, also share 20-year-old daughter Carys Zeta Douglas. Additionally, Michael is a father to 44-year-old son Cameron Douglas with his first wife, film producer Diandra Luker.

Dylan recently accompanied his dad to the Broadway opening of Good Night, Oscar, where he jokingly put the Wall Street actor on blast for his cringey dad jokes.

While walking the red carpet, Dylan told reporters that his dad's jokes "can be embarrassing sometimes, " though he said it's mostly "in terms of what he says, rather than who he is."

"Just dad stuff. [He’s a] bit out of touch, bad jokes for sure!" he said at the time, as Parade previously reported.
