Sienna Wants Babbies

Sienna Miller's sister, fashion designer Savannah Miller had her baby shower, where little sis Sienna spilled the beans on babies and her boyfriend Rhys.

Sienna Miller on babies: "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."

Fans, do you have any idea what scares Sienna? Say, she's afraid of being unable to be a wise manager of her time to do an actress and mommy duty. Hell, no! She might only be afraid of breast feeding...
