HOLLYWOOD — It had been four and a half years since Blink-182 performed together on a stage — at a December 2004 gig in Dublin, Ireland, to be exact. Well, now it's been nearly 12 hours.

On Thursday night, the reunited Blink returned to the stage at a T-Mobile party at the Paramount Studios, ripping through a surprise three-song set before an audience of stunned (and thoroughly hyperventilating) guests.

Blink tore through "The Rock Show," "Feeling This" and "Dammit," showing no signs of rust (or any ill effects of their sometimes contentious breakup), as they laughed, struck rock-star poses and cracked jokes.

"This is our first show after hating each other's guts," bassist/singer Mark Hoppus announced after "The Rock Show," to the delight of all in attendance.

The surprise Blink show capped off a night that also featured performances by Weezer — who will share the bill with Blink and Fall Out Boy on a rather ginormous summer tour — and Blink drummer Travis Barker's side project, TRVS/DJ-AM. Barker, ever the iron man, didn't even leave his kit after his hourlong set with DJ AM, drumming right into the Blink performance.

MTV News was there, and will have more news, photos and video from the surprise Blink gig — interviews with the bands, performance footage from the big reunion show — later in the day. But if you want even more, Hoppus has already posted several pictures from the party on his blog, and wrote about his reactions to returning to the stage. Hint: He felt good.

"To be honest, it was one of the best nights of my life," he wrote. "Thanks to everyone who was there. Thanks to T-Mobile. And most of all, thanks to Travis and Tom. You are my brothers, and it feels amazing to share the stage with you once again."
