The 76-year old actor posted a TikTok video of himself and his three grandchildren dancing to “When I Grow Up” by Pussycat dolls on Sunday.

The sweet shot was captioned by Happy Days alum “My grandchildren”. The clip was filmed in a living-room setting and features the children standing in line in front of their grandfather. Winkler then moves out of frame, as the music picks up. The group then jumped back in front of Winkler to dance and jump as the music went on.

Winkler joined TikTok on November 2020. He started posting lighthearted videos of himself dancing around the house, and spent time with his dogs. His grandkids are featured in the latest video.

Since 1978, Winkler has been married with Stacey. They have two children, Max, who is 38, and Zoe Emily (42). Jed Weitzman is 51 and he also has a stepson, Jed Weitzman. He was born to Howard Weitzman’s former marriage.

Parade interviewed Winkler in 2014 and revealed that his grandchildren did not know that he was an actor.

The four-time nominee for the SAG Award replied that the children didn’t know he was in showbiz. They only know me as Papa!

Parade was also told by Winkler that open communication is the key to their happy marriage over the years.

“I must tell you something. The ear is at the heart of all relationships, I believe. Barry said that it is not the heart or the mind. It’s the ear. Listening is both the beginning and end.
