Mario Lopez and his girlfriend, Courtney Mazza, are expecting a baby, but the couple wants a little "Extra" surprise on the Big Day — the sex of their child. Still, Courtney has a maternal instinct as to whether she'll be buying blue or pink. "I feel like it's a boy!" she told In Touch at a Svedka Vodka event in Hollywood on May 22. But her TV star beau has a different idea. "That means it's probably going to be a girl," he laughed. For now, the couple is focused on nesting and preparing for their bundle of joy's September arrival. "We got a new place, my sister is moving into town with her three kids and we got a new little dog," Mario says.
