50 & Paris Hilton At Sundance

Not many people over power 50 Cent, but thats what his entourage had to do on Saturday night to get him off the Park City stage " because he was enjoying himself so much!

He joked with the crowd, brought a live band on stage and even donned a cowboy hat as he treated the audience at the Myspace party to a 2 hour set of his greatest hits.

And MTVNews can report that his number one fan, at the front of the crowd, dancing throughout, taking pictures on her phone was.. Paris Hilton!

Yes, the heiress " alongside sister Nicky - displayed her, um, unique moves including head-banging that famous blonde bob to an acoustic version of Ayo Technology. Oh my god Im having such a good time " this is the best Sundance ever!

Paris told us moments before taking her spot in the mosh pit.

Joining 50 and the Hiltons in town were Colin Farrell the Olsen twins, Josh Hartnett, Tom Hanks, Method Man, Kim Kardashian and Jessica Alba, who walked between cafes and shops amongst the hundreds of fans on the street.

It seems Sundance brings out the best in people. Or should that be brings out the best people..
