DJ AM, Travis Barker and Blink-182 Rock for T-Mobile

Nothing like a nifty new piece of gadgetry and some boss tunes to bring the celebs out in droves. 

T-Mobile threw its Party Celebrating the New Sidekick LX on the Paramount Studios backlot in Los Angeles on Thursday night, drawing a slew of stars for a night of technological appreciation and top-notch musical entertainment.

Paris Hilton and her beau Doug Reinhardt, Kim Karashian, Nikki Reed, Alex Meraz, Zachary Quinto, Pete Wentz and Ashlee Simpson, Pink and Kelly Osbourne (rocking a super-short, platinum hairstyle) were among the notables on hand for the event, which featured a performance by collaborators and plane-crash survivors Travis Barker and DJ AM.

When the duo—who drove attendees wild with their performance—finished up their set, guests were treated to a very special surprise performance. Barker’s once-and-current blink-182 bandmates Tom DeLonge and Mark Hoppus joined their drummer on stage for an unannounced three-song set, giving audience members a taste of what to expect on the reunited band’s upcoming summer tour.

Sounds like an awesome night.
