Aaaah, how cute! Kristin Cavallari looked blooming as she stepped out in LA yesterday after a meal at The Cheesecake Factory Restaurant. Showing off her perfectly formed baby bump in white skinny jeans, a grey t-shirt, printed scarf and black jacket, the four months pregnant Hills star looked amazing. Well, she should do - her and fiance Jay Cutler have just returned from a lovely relaxing holiday in Mexico. We just wish we could get some of that pregnancy glow (without the actual pregnancy bit).
