Here’s new mom Rachel Bilson heading to a birthday party in Beverly Hills the other day, and looking like the most adorable and cutest mom on the entire freaking planet while doing so. Yet again. But what’s relatively new this time is that she look bustier than ever. And it’s all thanks to Hayden Christensen knocking her up. Ummmmmm, I can’t believe I just said that. Ok, so forget about that improper behavior and enjoy the photos!
