Travis Barker Talks Grammy Performance With Eminem, Lil Wayne, Drake

'I have yet to rehearse,' Blink-182 drummer tells MTV News of his performance at Sunday's show.

Travis Barker is eternally busy. Blink-182. Solo album. Clothing company. You name it, he's probably got his hand in it. That's why you can't blame him if he's not totally up to speed on his performance with Drake, Lil Wayne and Eminem at Sunday's Grammy Awards. Sometimes, these things tend to pile up.

"I have yet to rehearse [with anyone]. I got a call, like, on Tuesday. Everyone found out a day after I did. So, I don't know exactly what I'm doing yet," Barker told MTV News on Friday (January 29) in his Los Angeles studio. "I'm just a part of it. I know I'm playing drums. I know it's a performance with Eminem, Drake, myself and Lil Wayne. I think it might be 'Forever.' "

That seems likely. After all, both Em and Wayne contributed verses to Drake's "Forever," and Barker contributed a blazing remix of the song earlier this year. But the Blink drummer's night won't just stop there. He's apparently also set to perform with Wayne on a version of "Drop the World," from Weezy's upcoming Rebirth album (that track also features Em), which makes it sound very much like there's a medley on tap.

"Yeah, I think we're doing a medley, a couple of songs," Barker laughed. "I think 'Drop the World' is in. Maybe."

And while a combo of Barker, Drake, Eminem and Wayne would certainly rival the "Swagga Like Us" performance at last year's Grammys (which featured Jay-Z, Kanye West, T.I., Weezy and M.I.A. sharing the stage), there's still one big question: Will West — who has been lying low since his infamous outburst at the 2009 MTV Video Music Awards — show up on Sunday to perform his verse on "Forever"? Not surprisingly, Barker isn't exactly sure.

"I don't know. Someone said he's in Hawaii, writing an album," he smiled. "I would stay there."
