Forget MTV's "Hottest MC" list, Kendrick Lamar is getting the ultimate co-sign by the legendary rapper himself, Jay-Z. The 'Watch the Throne' creator will appear on the remix of 'Bitch, Don't Kill My Vibe.'

Producer Young Guru unveiled the song during a DJ set at SXSW in Austin, Texas. After listening to the tune, we think fans will be pleasantly happy with Hov's verse.

"Name one n---- out there harder than me, I'll wait," Jay-Z spits on the 'good kid m.A.A.D. city' track. "I've been that way for like 20 years straight / I've been on my vibe for like 20 years straight / Don't f--- up my high / F--- up my eye / Night like this I'll f--- up the pies."

According to Spin, K.Dot and Jay are to set to perform at Yahoo! Fest this summer. So we're crossing our fingers and hoping that these two hot emcees will perform the song together during the event.

There's no official word on when the 'Bitch, Don't Kill My Vibe' remix will be released. Currently, the Compton rapper is promoting his latest single, 'Poetic Justice.' Lamar recently performed the song live with Alicia Keys, who provided the Janet Jackson-sampled hook.
