20 Hottest Female Celebrities Under Thirty

Naya Rivera

We saw Naya Rivera grow up during her time on Glee, as she seemed to get more and more beautiful each season. The 28-year-old also seemed to get more and more in shape and she definitely likes to show those abs off.

Kate Upton

Kate Upton is best known for her photo shoots for Sports Illustrated, but she has ventured into the acting world with her role in The Other Woman. Was anyone really paying attention to her acting skills though or was it more about those boobs on the 22-year-old?
