Robert De Niro literally dives into 81st birthday

Robert De Niro turned 81 on August 17, and he's diving headfirst into it. Well, almost.

The legendary actor's eldest daughter Drena posted a Happy Birthday message complete with video of the Oscar winner diving off a boat into the water. Although he started off headfirst, he didn't quite stick the landing, making a huge splash.

"He's so crazy!" she admonished him for the stunt from the deck above him, laughing, adding, "Oh my God, are you all right?"

"I'm OK," the Wading Bull said after he surfaced, and began treading water.

"Happy 81st Bday to my Dad and #1 ride or die .. Love you with all my [heart]" she captioned the post, adding, "#BobbyD forever."

"Happy Birthday to the king of the jungle," she wrote alongside a photo of her in a white dress perched up in her father's arms.

Another photograph on Drena De Niro's Instagram Story shows her and her father arm-in-arm in formal attire. "Happy Birthday to my favorite Fella," the text on the photo read.
