VIDEO: Security guard becomes unlikely star at Lady Gaga concert

It's fair to say that if you go to a Lady Gaga concert, your eyes are going to be glued to the stage.

The Born This Way singer puts on such an incredible show - with wild costumes, hair, make-up, props and stunts - that there's little else you'll want to look at.

But one fan attending her brand new Enigma residency in Las Vegas managed to tear his eyes away long enough to catch one of the security guards singing along to a lesser-known song.

Actor Marc Cohen, from Los Angeles, shared a video of a male security guard passionately miming along to Lady Gaga's performance of Beautiful, Dirty, Rich.

Marc claimed this hilarious moment was "one of the best parts" of the show.

His Twitter post read: "One of the best parts of Enigma was this security guard knowing the lyrics to Beautiful, Dirty, Rich and not caring he knew it!"

So far over 19,000 people have liked the video, with more than 4,000 sharing it.

A woman named Catie responded to Marc claiming she'd also spotted the singing security guard.
