Heather Morris is best known for the odd one-liners her character Brittany recites on 'Glee,' but her first passion is dance and she's pretty freaking good at it. Morris shows off some of her smokin' hot moves for Esquire's '50 Songs Every Man Should Be Listening To.'

Morris, clad in a skin-tight, partially sheer leotard, shakes her groove thing to the likes of 'Heart Attack' by Raphael Saadiq, 'Rock N Roll' by Raekwon and 'Sofi Needs a Ladder' by Deadmaus in a seductive rock 'n' roll shoot that's a far cry from her days as a cheerleader.

What many may not know is that Morris was never supposed to be part of the 'Glee' cast. A dancer since she could walk, Morris served as a 'Single Ladies' backup dancer for Beyonce and the show's producers brought her her in to teach the cast the signature dance in 2009.
