Before Pharrell Williams' "Something in the Water" festival kicked off this past weekend, the N.E.R.D. star partnered with Usher for a little fun before the madness began. The famous pair invited friends and family to the Haygood Roller Skating Center in Virginia Beach, Pharrell's stomping grounds, for a private party. According to TMZthere were a little over 100 guests including "Pharell's parents and relatives, Pusha T, Fergie, D.R.A.M., Young Money Yawn, Bruce Smith, Aaron Rouse, Dallas Austin and Pernell 'Sweet Pea' Whitaker."

To say thanks for hosting their private shindig, the Haygood Center was given a gift of an autographed roller skate, signed by the famous faces who attended the party. In a clip of the event, you can see the cocktails were flowing and everyone was having a great time, especially Usher who was captured getting his roll on to Vaughan Mason & Crew's 1979 hit "Roll, Bounce, Rock, Skate."

"Something in the Water" would get off to a rocky start as weather derailed the first day, but the weekend would later pick up with performances by Jay Z, Diddy, Snoop Dogg, Missy Elliott, Busta Rhymes, Timbaland, Charlie Wilson and Tyler, the Creator.
