Oscar winner Charlize Theron is putting off motherhood for as long as possible - because she doesn't want to look like "a whale". The Monster star admits she has confusing thoughts about parenting - because she knows she'll be a mum one day. The 32-year-old actress says, "Getting pregnant doesn't excite me, but having kids does. I know I'll be a mother one day. "It's just that I don't really want to look like a whale. "But I'm sure the idea of something growing inside you is pretty powerful."
