The “Lady Marmalade” R&B diva Patti LaBelle has been accused of hurling curses and throwing water at a toddler, according to a lawsuit filed at Manhattan Supreme Court on Monday.

The mother of the toddler claims her daughter suffered from personality changes, including sleeping disorders and increasing fear of strangers, ever since she was left terrified by the singer.

LaBelle has not responded to the lawsuit yet.

On Nov. 11, 2010 afternoon, Roseanna Monk put down her 18-month-old daughter to carry some luggage out of a Manhattan building, where LaBelle stayed for a time while she worked on the Broadway show 'Fela!', according to the lawsuit.

LaBelle chastised the mother for letting her kid running around the lobby when she walked into the building and admonished her to put her daughter by the door, Monk said.

I have no interest in what you say or think, she responded to the singer.

Then the singer threw a half bottle of water at Monk and her daughter and hurled a profanity-laden tirade.

Are you happy that this is what you have done to this baby, Monk asked the singer after her daughter began crying. Then the singer swung punch and tried to hit her, according to Samuel L. Davis, Monk’s lawyer.

Monk subsequently filed a complaint with police but no arrests were made.

After reading about an incident that a 23-years-old West Point cadet was attacked by LaBelle's bodyguards in a Houston airport, Monk and her husband decided to sue LaBelle,because they feel “someone’s got to teach her even a diva can’t attack and frighten and assault regular people in the building.”

The cadet Richard King accused the star’s bodyguard and hairdresser of attacking him.

LaBelle counter-sued the cadet by saying the drunk young man tried to get into her limousine and used racial slurs, which he has denied.

The two times Grammy award winning singer is known for hit songs including 'Lady Marmalade', 'I'll Be Your Friend' and 'Tries To Take a Swing.'
