David Arquette's ex-wife, Courteney Cox, (accidentally?) revealed that he's having a baby boy with girlfriend Christina McLarty on The Ellen DeGeneres Show Tuesday — but Breaking Celebrity News readers already knew that, because we exclusively told you first!

"They’re going to have a baby boy," Cox told Ellen DeGeneres. "I hope I’m allowed to say that!"

Arquette and Cox have a 9-year-old daughter, Coco, together from their 1999 marriage and the former Friends star said she can't wait to be a big sister.
