50 Cent is reporteldy planning to file a defamation lawsuit against his ex-girlfriend for accusing him of burning down his Long Island Home.

As reported earlier, the multi-million dollar home was destroyed by a  fire in the early morning hours of May 30th.  Six people who were in the house including 50 Cent’s ex-girlfriend and his son were rushed to hospital and treated for smoke inhalation.

After being released from hospital, 50 Cent's ex-girlfriend, Shaniqua Tompkins,  publicly claimed that the rapper orchestrated the fire.

According to The New York Daily News, 50 Cent's lawyers have begun working on a defamation complaint against Tompkins for the allegations.

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

50's lawyers also claim Tompkins has refused to let the rapper speak to his son or know where he is currently residing.

50 Cent and Tompkins have been fighting over the house afte r the rapper attempted to have her evicted from the home unless she paid rent.  Tompkins retaliated by filing a breach of contract lawsuit claiming that the rapper promised to buy her the house.

Fire officials who arrived at the house to distinguish the blaze called the fire 'suspicious' and determined it as arson.  A 5-gallon gas container would also be found on the grounds.  Their investigation is still underway and neither 50 or Tompkins have been named as suspects.
