Kendrick Lamar has scored the ultimate guest feature with Jay-Z appearing on his 'Bitch, Don't Kill My Vibe (Remix).' The Compton rapper is mum about the collaboration but is honored to have his idol on the remix.

"Ah, man, I can't really speak too much on it, I just know it's in the air right now," he told MTV News about the track. "I can't -- it's under wraps. It's all love. That's the big homey. It's one of them things, you know, you live up to and one of them moments to really challenge yourself and say, 'OK, that's how I come in. Always looked up to the greats to be a great.' So to actually be on a track with him, it's an accomplishment."

Jay-Z's longtime engineer and producer Young Guru spilled the beans on the duet when he spun the song during a party at SXSW. The song has generated online debates on who had the best verse -- K.Dot or Hov?

No word on when the remix will get its official release. 'Bitch, Don't Kill My Vibe' will most likely be the next single from Lamar's celebrated album, 'good kid, m.A.A.d city.'

Meanwhile, Lamar and Jay-Z are set to co-headline the Yahoo! on the Road festival this summer. The 21-city trek will kick off in America on May 3 in New York and wrap up in London with six concerts scheduled for July 9-14. Macklemore and Ryan Lewis and J. Cole are also on the bill.
