"They're going to be amazing [parents]. I can't wait to see her and give her a big hug," says Marini, who found out about the news after his performance on Dancing Tuesday night.
As for the girls, he predicts,"They're going to be beautiful – and on top of everything, they're going to be extremely smart."
But it's possible that Marini and Parker will have more to talk about than just babies soon. Rumors have been swirling that Marini could be returning for more steamy scenes in the SATC sequel.
Still, nothing has been confirmed, says Marini. "I would love to do it because I think it would be a great opportunity for all of us," he says. "As soon as it's confirmed, trust me, you'll know."
