49. Michelle Pfeiffer
Quintessential Californian beauty Michelle Pfeiffer once told The National, "[The] good part about turning 50—is that it's really not such a big deal. You spend so much time dreading it and there's so much talk about it and then it comes and goes and it's over and for me it's been incredibly liberating. It is really letting go of the need to stay young for ever and the need to be perfect."
