According to The New York Post, Cooper (who turned 38 on Saturday) split with Saldana before the holidays, leaving the spot for his Golden Globes date open for a special lady.

"I heard you were bringing your mother [to the Golden Globes]," said Hart, who led the audience in singing Happy Birthday to Cooper just moments before their interview.

Playing the protective son, Cooper explained that he's still undecided due to the atmosphere.

"She's a young woman, but it hard to navigate," said the Silver Linings Playbook star, who was nominated for Best Performance by an Actor in a Motion Picture - Musical or Comedy. "It's like a zoo, so I think it's not the best place."

Presented by Cartier, the 24th Annual Palm Springs International Film Festival honored Naomi Watts, Robert Zemeckis, the cast of Argo, Helen Hunt, Sally Field, Richard Gere, Bradley Cooper, Life of Pi composer Mychael Danna, Les Miserables director Tom Hooper and Helen Mirren.

In her tenth time hosting the PSIFF, Mary Hart once again pulled double duty as emcee and ET correspondent. This gave the stars a chance to interview each other backstage when Mary was called back to the podium!
