Cougar Alert!

Courteney Cox and Demi Moore could have passed for twins last night as they arrived at the 'Glamour Reel Moments' premiere in Hollywood.

Both stars who are in their forties showed every girl in their twenties how to do it right. Meow ladies, meow.

Both Cox and Moore were sporting sexy black dresses. Like Hollyscoop mentioned yesterday, you can't go wrong with a black dress!
