LOS ANGELES, California (The Adobo Chronicles® )  – Singers Nicki Minaj and Miley Cyrus have filed a joint lawsuit in Los Angeles against Patti Labelle, claiming the 71-year-old diva  defamed their good moral character with comments she made at a recent concert.

The “New Attitude” diva ripped into a fan after he started to strip onstage during her concert Friday night at the Hard Rock Casino in Vancouver.

While performing the hit “Lady Marmalade,” LaBelle invited several audience members onstage to dance. However, according to a video obtained by TMZ, when one man began to unbutton his shirt, the singer immediately scolded him.

“Don’t you dare, not on my stage,” she commanded, adding, “I am 71-years-young I am not Nicki Minaj or that little, uh, Miley.”

“The insinuation in Labelle’s comments is that we are cheap ‘sl*ts,’ ” the complainants said in a statement.

Labelle could not be reached for comment.
