Lady Antebellum's Hillary Scott celebrated her 25th birthday at The Bank Nightclub in Las Vegas on Friday. Lady A guitarist Dave Haywood, Kellie Pickler and Rascal Flatts singer Gary LeVox were all there to help blow out the candles. Hillary and Kellie burned off their cake calories with a little dancing afterwards. See a great picture of the ladies showing off their dance moves (and a lot of leg!), after the jump.
