More baby mama drama for 50 Cent. The rapper is going to court to stop Shaniqua Tompkins, mother of his 11-year-old son, Marquise, from claiming he masterminded the suspicious blaze that destroyed her Long Island mansion last month.”He tried to kill me and his own child,” Tompkins has declared. “I know this came from 50 Cent.”While arson investigators probe the Dix Hills fire, Fitty’s legal team is drafting a defamation complaint against Tompkins.
“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.”

The hip-hop king (real name, Curtis Jackson) charges that since the fire, Tompkins has refused to let him see Marquise or tell him where he’s living. Tompkins has “made it practically impossible” for 50 to speak to or see his son, according to a petition filed this week in Suffolk County Family Court. 50 says that when he learned Marquise’s cell phone was destroyed in the fire, he sent him a new one, along with a duffle bag of new clothes.
Tompkins has “failed and refused to give the cell phone to Marquise,” 50 alleges. “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.
50 says her behavior is a “willful violation” of their custody agreement and is asking for a court order to put him back in touch with his boy.
The rapper’s lawyer is due in court tomorrow for a hearing. 50, who has been in Louisiana filming “Microwave Park” with Sharon Stone and Val Kilmer, isn’t expected to attend.
Tompkins’ lawyer didn’t return a call.
