Rachel Bilson and her mom Janice Stango took a walk on Friday after grabbing lunch in Los Angeles, and earlier today the news broke that the former OC starlet is expecting a girl with partner Hayden Christensen!

Of course, a rep for Bilson denied the report, calling it speculation and gossip," but we're guessing this was the same source who told People that Bilson had a bun in the oven, and as you can see from the size of her baby bump, that turned out to be true!

And not only that, but it seems as though she dropped a hint about her pregnancy back in May when she told Health Magazine, "I didn't eat beef for three years, but I recently started eating it again because I needed iron. So this is the latest thing we do, with vegetables from my organic garden. It's so yummy." Funny, because it's widely known that red meat is one of the best sources of iron for pregnant women...

She definitely had babies on the brain, because she also added during the interview, "I've always looked young because I'm so short, and especially if I'm dressed down. When I have a baby, everybody's going to be like, 'Awww, poor teen mom. Poor girl.' And Teen Mom is my favorite show. That's what I download and watch on the plane. Like, don't talk to me, I'm watching Teen Mom. I know, pathetic. But it's true."
