AceShowbiz - Fatherhood at elder years has seemingly taken its toll on Robert De Niro. Having recently welcomed a baby girl with Tiffany Chen, the actor and his girlfriend looked exhausted when stepping out for a red carpet event.

On Wednesday night, June 7, the 79-year-old actor and his 45-year-old girlfriend attended the premiere of "Kiss the Future", which marked the kick-off the Tribeca Film Festival which he co-founded in 2002. As they walked the red carpet, the pair didn't look too excited.

Both Robert and Tiffany mostly kept stoic expressions on their faces while posing for the cameras. He also seemed to be eager to quickly end the photo session as he was ready to leave the red carpet, before the press asked them to stop for a while to take their pictures.

The "About My Father" star, however, kept paying attention to his baby mama as he was holding her hand while walking the red carpet at the star-studded event.

Robert wore a dark gray polo shirt, black jacket and black pants for the premiere event. Tiffany, meanwhile, sported a black dress, an oversized beige cardigan and nude pumps. She completed her look with a pair of sunglasses and a pink Chanel handbag.

At the event, they mingled with attendees like Debra Messing, Brendan Fraser, Kate Siegel, Noah Centineo and Stephen Kay. Matt Damon and Ben Affleck, who produced the documentary about an American aid worker living in Sarajevo, were nowhere to be seen at the film festival that night.

Robert just became a father again at age 79 after Tiffany gave birth to his seventh child and their first together on April 6. He casually spilled the news during an interview with ET Canada in May. The first official picture of the baby girl, who's named Gia Virginia Chen-De Niro, was later released on "CBS Mornings".

Robert also shares adoptive daughter Drena, 51, Raphael, 46, and 27-year-old twins Julian and Aaron with ex-wife Diahnne Abbott as well as Elliot, 25, and 11-year-old Helen Grace with second wife Grace Hightower.
