Break Out The Flour!

We hope that's a fake fur Katherine Heigl's wearing but we kind of suspect it's not! Isn't she afraid of flour-wielding PETA activists?

Well, I guess we'll give her the benefit of the doubt only because it was her birthday yesterday.

Even though she officially celebrated it with an old Hollywood party last weekend, we caught the new 30-year-old out for dinner with her husband Josh and her co-star Justin Chambers.

But who's the blonde with Justin? Definitely NOT his wife and the mother of his five children, that's for sure!
