Singer and "Love & Hip Hop ATL" reality star K. Michelle displayed some extra ratchet behavior during a live show recently when she cursed a fan out and threatened to whoop his a** while on stage! Watch K. Michelle let the hood get the best of her inside....

Talking smack about K. Michelle "could" get you hurt, at least that's what one fan found out during a recent K. Michelle live show.

The singer and reality star was caught on tape making threats from the stage after a fan apparently started talking trash about her on Twitter WHILE she was on stage performing.

You have to wonder how she knew what was going down on Twitter while she should have been focused on her audience...but she did. She called out the fan's Twitter handle (apparently a male) and said, "I will take off my heels, snatch off my lace-front and whoop your a**.”  And judging from the applause, the audience seemed to enjoy the profanity-laced tirade.  Another version of her "shaking tables" we guess.

This may not be her normal behavior and perhaps K. Michelle is just ramping up the drama for her season 2 story line on "LAHH ATL."  We just hope no fans get hurt in the process.........

Watch the clip here:

Chick looks like she's channeling early 90's MJB.  Gotta love it...
