Sienna Miller couldn't hide behind her pink quilted bag as she made her way through LA the other day. She didn't have her fiancé Rhys to escort her, but her man is never far from her thoughts. In fact, Sienna is already thinking beyond her wedding day to babies! When asked about having kids of her own at her sister's baby shower, Sienna said, "I really want bubbies — I always have. I mean, I'm 27 and you have to think about these things, don't you? And Sav (sister Savannah) proves you can work and be a mum. It still scares me, though." Sienna loves a good party and she's still young, but we'd love to see how this stylish star would dress with a growing baby bump.
