Leonardo DiCaprio also attended the birthday party, which was held at De Niro’s Tribeca restaurant, Locanda Verde, on Thursday, People magazine reported. De Niro and DiCaprio star together in Scorsese’s upcoming film, “Killers of the Flower Moon.”

De Niro’s daughter Drena, 51, shared birthday wishes for her father on her Instagram story ahead of the bash. The outlet reported she re-shared a post by Debi Mazar, writing “Happy 80 you know who!”

De Niro became a new father again in April at the age of 79 when he welcomed a child with Chen.

The baby girl, named Gia Virginia, is De Niro’s seventh child.

Despite De Niro’s big birthday bash in NYC, most actors have only been stepping out to join the picket lines in support of the ongoing writers and actors strike. Mandy Moore, Mark Ruffalo, Jason Sudeikis and more have been spotted with signs.

Leaders of the actors’ union voted to strike on July 13, creating a joint strike with the entertainment industry’s writers for the first time in six decades.

The strike rules prevent actors from making personal appearances or promoting their work on podcasts or at premieres. And they are barred from doing any production work including auditions, readings, rehearsals or voiceovers along with actual filming.

The month of August in Hollywood is typically filled with charity events and other bashes, but “people are just not wanting to be seen out and about,” an insider told The Hollywood Reporter.

“We’re seeing a mixed bag with people’s individual comfort level,” another source told the outlet. “Some people are just sitting some things out altogether.”
