The hitmaker was performing Whatever You Like when the male fan allegedly touched his backside.

The stunned rap star reprimanded the handsy devotee, snarling, "Don’t put your hands on my a** again, bro.

"What the f**k is wrong with you, n**ga? I will f**k you up! Never touch my motherf**king a**... We came to have a good time, but I ain’t with the disrespect."

Footage of the moment T.I. lost his cool has been posted online.
