I mean it's definitely not something I would have expected, but John Travolta still got the moves though!

According to USA Today 50 was performing at an afterparty for the premiere of Travolta's new movie Gotti.

Pitbull was supposed to perform, but got sick and had to cancel. 50 stepped right in and had Travolta steppin' out.

According to the report, Travolta said this about his dance,

"The dance was just whatever I felt at the moment, it doesn't really have a name to it. It's just being cool, I guess."

50 cent tweeted out the video of Travolta's moves and said the star of Saturday Night Fever, is the only reason he came to perform. Check out the tweet and video here:
