Paris Hilton Throws Glitzy Party On Santa Monica Pier

Paris Hilton turned the Santa Monica Pier into the biggest party in Tinseltown Friday night ... boogying down and DJ'ing on stage in front of thousands of fans.

The reality star/entrepreneur rented out the entire Pier to celebrate last year's launch of her company, 11:11 Media. The bash was Paris through and through -- lotsa glitz and glam!!

Paris hit the stage for the DJ thing and the crowd ate it up, cheering her on and shooting cell phone videos. She then brought out the DJ master -- Diplo -- to take the reins as she began twirling for the audience.

The Hilton family -- Kathy and Nicky -- was also there, lapping up all the fun. And so was Paris' husband, Carter, who tried to coax his wife off stage to eat some cake to celebrate their first anniversary. But Paris wasn't having it ... she was in the moment.

Guests at the party were greeted at the door by a Paris Hilton Proto hologram. Some in attendance were Zedd, Tiffany Haddish, DJ Nice, Rebel Wilson, Ryan Phillippe and more.

Everybody was treated to In-N-Out burgers and gifts ... Paris' new fragrance Love Rush and blinged-out water bottles.
