Grey's Anatomy doc Sydney Heron has a bun in the oven - in real life.

Kali Rocha tells TV Guide that she's three months along. "I'm pregnant!" a glowing Rocha, patting her barely there baby bump, said at Tuesday's premiere of

Over My Dead Body. Asked if she had an inkling on whether it's a boy or a girl, Rocha said, "I keep hearing this theory that if you look very rounded in the face and you [get sick] a lot, it's a girl. I have a round face all the time, but I didn't [get sick] once. The theory also says that if you are feeling good and have a square jaw, it's a boy. So I have no idea. Maybe I have a hermaphrodite." Look for Dr. Heron to return to Grey's sometime in the future. - Clare Kleinedler For more from the premiere of Eva Longoria's Over My Dead Body, including news of American Pie star Jason Biggs' engagement, see the Party Central blog.
