Nick Cannon in the deejay booth at Gallery Nightclub.

Nick Cannon made his DJ residency debut as Adrian Grenier, Scott Disick and Rob Kardashian stopped in to party last night at Gallery Nightclub at Planet Hollywood Resort.

The multi-talented Cannon had revelers hyped up, spinning and remixing tracks like “New York, New York,” “California Love” and “In Da Club.” The entertainer got things hot when he yelled out to the crowd on the DJ booth mic, “The hottest place in Vegas is Gallery! Let’s go, people!” Cannon was seen sipping on Evian as he kept the club going crazy until the early morning hours.

Also spotted was “Entourage” star Grenier. The HBO actor was in Vegas celebrating the premiere of his documentary, “Teenage Paparazzo.” The director and actor looked handsome in a checkered button-up shirt and jeans as he sipped on Grey Goose with orange juice and enjoyed the tunes being spun by Cannon.

Disick and Kardashian were also seen in the VIP area. The reality stars, in town for Kim Kardashian and Kris Humphries’ bachelorette and bachelor parties at Lavo at the Palazzo and Tao at the Venetian, were drinking Veuve Cliquot and Grey Goose as they relaxed at their private table with a few friends.
