The temperatures were sizzling over the weekend in Vegas, but AnnaLynne McCord along with her sexy sister, Angel and boyfriend, Kellan Lutz certainly turned up the heat!

The three hotties were at MGM's Wet Republic to celebrate AnnaLynne's 23rd birthday. Unfortunately, the birthday girl and her BF kept their clothes on, but get a load of Angel's amazing body.
