14. Hilary Duff – 28
Hilary Duff is yet another actress that seems to have put on years following the birth of a child. Hillary was best known for her child roles in television and movies before she moved on to focusing on her music career. Both her endeavors have proven to be successful, but the actress is starting to show the stress of being a busy mother. She is 28, but by Hollywood standards she looks very much younger. Maybe she can call upon her cartoon alter ego whenever she starts to really look old.
