Minnie Driver announced her pregnancy
on The Tonight Show
– and now she's chatting with Ellen DeGeneres
about the biggest dilemma facing her right now: what to name her baby.
"I have a pretty silly name," the Riches
star says on an episode of the Ellen DeGeneres Show
scheduled to air Monday. "Driver is kind of a hard name to put with a first name, particularly boys names … My friend sent me an email saying I should call the baby Duncan Driver. Then I can call it Dunk Driver, Pile Driver, Rally Driver."
Joked DeGeneres: "So you’re hoping for a girl, you're
"I'm hoping for a girl," Driver answered. "I think it's a girl. Most of the women in my family get super girthy early on and I've got to say that's why I have this nice chiffon dress on. I'm fat. "
Already "four [months] and a bit" along in her pregnancy, Driver, 38, tells DeGeneres why she waited to reveal it – even as speculation grew. "I didn't do an announcement because I'm not really an announcement girl," she said. "I'm wearing red knickers. I'm also having a child, not really my thing. So I didn't say anything."
Another thing Driver did not mention: The father of her baby.
