British babe Sienna Miller says she's desperate for kids and blames her sister's attitude towards motherhood for her recent obsession.
She says, "I really want bubbies (babies) - I always have. I mean, I'm nearly 27 and you have to think about these things, don't you? Sav (sister Savannah) proves you can work and be a mum. It scares me, though."
Let's just hope the "bubbies" take after Sienna because her fiancé is kinda fug.
