Happy 44th birthday to the one and only Olivia Munn! Can you believe it? You've entered your "double 4" club and you're officially closer to 50 than 40. But let's be real, you still look like you're in your 20s. Is there a secret fountain of youth you're hiding? Anyway, cheers to another year of being fabulous, funny, and fierce. Keep slaying, birthday queen!
