The couple stepped out at a Vanity Fair party to celebrate the Tribeca Film Festival in New York on Tuesday, telling People that they don't know the gender of the little one, but are excited. "And it's due on my birthday," Rossi exclaimed.
Rossi's film Bad Hurt is set to premiere at the film fest, and the actor says he can't wait to be a dad and raise the baby in the Big Apple.
"I'm just excited for him or her," he said. "I'm just excited for this baby to grow up in New York City because it's the greatest place in the world, and it made me who I am, and I just think that it's going to be very interesting because it's a very different time from when I grew up."
