Confirmed in the final hour, 50 Cent will headline a Sundance lineup at Downstairs with heavyweights Lil John, DJ Mom Jeans (Danny Masterson) Swhazye and Dirt Nasty. If that wasn’t enough to crown the star-studded club the King of Sundance parties, the venue will also host the birthday celebration of cult classic Slick Rick and “That ’70s Show” star Wilmer Valderrama. The musical lineup also stars Park City favorites Miss DJ Lux, DJ Scooter, DJ Bentley and Moise Bentley. Unlike most Sundance parties, the “local-first” nightclub invites guests to enjoy the A-List parties, with RSVP inquiries and VIP reservations available at vip@downstairspc.com.

Among the beautiful people rumored to attend are Chloe Lane founder Michael Gribetz, Park City LOCALS socialite April Morrison, IN This Week’s Camila Grover and surprise celebrity guests.

Tickets go on sale later today, January 19!
