Robert De Niro celebrated his 81st birthday with a less-than-graceful dive off of a yacht, as captured on video by his eldest daughter Drena De Niro . “Happy 81st Bday to my Dad and #1 ride or die ..

Love you with all my ♥️♥️♥️ #BobbyD forever ✨👑✨,” Drena, 56, wrote via Instagram on Saturday, August 17. Her post featured a photo of Robert in midair as he leaped off the side of a yacht in orange-and-blue striped swim trunks. A subsequent video showed the Oscar winner diving off the boat, which was met with cheers from onlookers and Drena exclaiming off-camera, “He’s so crazy!” In the video, she called down to her dad to ask, “Are you alright?” He responded from the water, “Yeah, I’m okay!” Drena was also heard asking someone “how many feet” the drop from the boat into the water was, to which someone replied “30.

” Drena also shared photos of Robert holding her as a baby, as well as other photos throughout the years of the actor at the beach with his grandchildren. Robert adopted Drena when she was five years old after he married her mother, Diahnne Abbott , in 1976. Diahnne and Robert went on to have a son, Raphael, 47, before they divorced in 1988.

A post shared by Drena (@drenadeniro) Robert shares twin sons Julian and Aaron, 28, with ex-girlfriend Toukie Smith ; son Elliot, 26, and 12-year-old daughter Helen Grace with ex-wife Grace Hightower ; and a 16-month-old daughter named Gia with his current girlfriend, Tiffany Chen . “.
