Raunchy rapper Foxy Brown's trash talk on Twitter persuaded her long-suffering manager to dump the hip-hop queen - but not before vowing to sue her.
"It's always sad when an artist has everything they need at their fingertips but still displays such self-destructive behavior," Bernadette Brennan told the Daily News.
"I hope she gets the help she needs," Brennan said of her ex-client. "I was one of the few people in her corner."
Although Brown, 32, has released just one album since 2001, the platinum-selling performer still behaves like it's her '90s heyday, sources said.
Sources told The News that Foxy - whose real name is Inga Marchand - is becoming an industry outcast over her unreliability.
Foxy infuriated promoters when she appeared more than four hours late for a show at Splash Bar in Manhattan this fall, sources said.
And she blew off her own Christmas Eve event at Brooklyn's Jelani Lounge - a gig planned to highlight a new album that remains unreleased, sources said.
At the time, the "Ill Na Na" star went on Twitter to blame a last-minute change of venue for the missed gig.
"If she had any money, we'd sue her [for not showing up]," said one Manhattan nightclub manager.
Reached Tuesday night, Brown refused to comment. Marvet Britto of The Britto Agency, identified by Brown as her official mouthpiece, could not be reached for comment.
But over New Year's Eve and New Year's Day, the Brooklyn bad girl rapper sent a series of tweets ripping Brennan as a "thief" and promising her own lawsuit.
"I will see all yall snake motherf------ in court!!!" she wrote on Dec. 31.
Brown denounced Brennan as a fake manager, adding that only her family represented her.
Brennan said she plans to sue Foxy for costing her more than $100,000 in studio fees, among other expenses.
The two were once close. Brennan bailed Foxy out of jail and took the rapper into her Manhattan home last summer after a bizarre mooning incident with a neighbor on Brown's Brooklyn block.
The manager even backed Brown after a July meltdown in the lobby of her posh midtown high-rise, where the hip-hop star reportedly tried to attack her.
Brown is due back in a Brooklyn court next month on a criminal contempt charge in her confrontation with neighbor Arlene Raymond.
The rapper also spent seven months in jail in 2007-08 after violating probation in connection with a 2004 assault on a pair of Chelsea manicurists.
