50 Cent Sues Baby Mama For Defamation

Fifty Cent and his ex, Shaniqua Tompkins, are headed back to court again as the drama between the two continues to roar.

Fif wants the mother of his 11-year-old son Marquise to stop telling people that he's the one behind the early morning May 30 blaze at the Dix Hills home she lived in with their child and to let him see his son, according to New York's Daily News.

"He tried to kill me and his own child," Tompkins has declared. "I know this came from 50 Cent."

Arson investigators are looking into the fire as suspicious, but have not pointed the finger at Fif (born Curtis Jackson) as being involved.

His lawyers are accusing Tompkins of defamation.

"There comes a point where you can no longer sit on your hands and listen to her spread these falsehoods," 50's lawyer, Brett Kimmel, tells us. "Besides hurting his reputation, they have a damaging impact on their son."

Days after the fire, Shaniqua blasted 50 in the media, telling reporters he hadn't even called to check on his son. But in a petition filed this week in Suffolk County Family Court, Fif says Shaniqua has made contact with his kid "practically impossible."

According to the rapper, when he heard Marquise's cell phone was destroyed in the fire, he sent him a new one, plus a duffel bag full of clothes. He said Shaniqua didn't give Marquise the phone and makes it difficult for him to call his son on her phone.

"The only way [50] can communicate with his son is to call [Tompkins'] cell phone. On June 11 ... [she] did permit [50] to speak with his son. However ... she was hovering over Marquise, monitoring the conversation and, after a short while, she interrupted the conversation by taking the phone from Marquise and began yelling at [50]," who eventually hung up on her, the petition reads.

As previously reported, the million dollar house has been the center of a heated battle between the former couple. 50 purchased the home in January 2007 and tried evicting Tompkins in April of this year, demanding that she either leave or pay $4,500 in monthly rent. Tompkins then filed a lawsuit against the rapper alleging a "breach of contract" as she claimed he promised to put all or part of the house in her name.

In April a judge ruled in 50's favor and gave Tompkins until the end of the school year to vacate the premise.

Fif is currently in Louisiana filming Microwave Park with Sharon Stone and Val Kilmer and isn't expected to attend tomorrow's hearing. His lawyer will appear for him.
