*”Love and Hip Hop” veteran K. Michelle had a fan get a little too close to her, prompting her muscle to step in and put a stop to it…with a knockout punch.

Sources close to K. tell TMZ said the fan appeared to be drunk when he approached the reality star at her hotel early Sunday morning. When the guy got rude and too close, she warned him to back off.

But the fan reportedly kept trying to touch the singer … so her bodyguard punched him in the face and that was that.

Cops were called, but before they arrived the fan regained consciousness and quicly left the scene, so authorities will take no action, according to TMZ.
