WATCH: A Backstreet Boy totally getting down to his OWN song

Well, if you can't dance to one of your own songs, what can you dance to?

TMZ is reporting that Backstreet Boy, A.J. Mclean, was seen dancing to his old tunes at a nightclub in West Hollywood over the weekend.

The boyband star spent that night partying to a Nineties cover band, but when Backstreet Boy favourite, Everybody, started to play, A.J. goes totally WILD. 

This comes just four days after Kendall and Gigi were spotted dancing behind-the-scenes at the Balmain x H&M launch.
