Q-Tip had the surprise of his life when he was performing a sold-out Las Vegas show in 2008. While he was rapping his funky track "Vivrant Thing," Prince graced the stage to perform with him. And it was all caught on video.

The rare 2008 clip surfaced via Miss Info. In the video, Tip is performing "Vivrant Thing" at the Las Vegas House of Blues and out of nowhere, the Purple One showed up and picked up a guitar, and jammed out with the A Tribe Called Quest member.

DJ Scratch, who was also on stage backing up Q-Tip, was in shocked.

"Yo, while me and Q-tip were performing 'Vivrant Thing' in Vegas...this n---- Prince walked out on the stage, took the guitar from our guitar player and just started rocking!" he told Miss Info. "None of us knew he was there until he popped up on the stage.Then the n---- vanished like Batman, LOL!"

Scratch said the sound crew told him that Prince was in the balcony watching the show from the very beginning (the balcony was closed off) and had to jam with the Abstract when "Vivrant Thing" came on.

The video is so crazy, no pun intended. "Vivrant Thing" is from Q-Tip's 1999 album, Amplified.

Check out how Prince stole the show and how Q-Tip surprisingly (and impressively) kept his cool during the whole performance above.
