Who's The Hotter Cougar - Courteney or Demi?

Don't get me wrong, these women look fabulous for their age, but as they grow older, they're starting to grow more alike in my mind.

Is it that they're both hot cougs married to younger men? That they both have long brown hair? That their careers seem to be faltering at the moment? Or that they've both had the aid of botox?

Or maybe it's just that they were both at the Thompson hotel the other night, Demi with Ashton and Courteney with a friend.

Oh, and can you guess which one's "mom ass" this is?
