Patti Labelle Goes Nuclear On Stripping Fan

Patti LaBelle made it known loud and clear last night ... NO ONE gets on her stage and strips down.

LaBelle was in Vancouver Friday night and invited a couple of fans up on stage with her to sing and dance. However, one fan took things too far for Patti and started unbuttoning his shirt, a big no-no.

Patti chewed the fan out and once he turned his backside to her, she lost it -- throwing him out of the show.

The 71-year-old even mentions Nicki Minaj and Miley Cyrus in the tirade -- LaBelle has criticized the pair's clothing (or lack there of) in the past.
