Let's get ready to rumble! 50 Cent's ex-girlfriend/mother of his son 11-year-old son, Shaniqua Tompkins, has slapped the rap star with a $50 million lawsuit, according to media reports. Tompkins is seeking damages related to a fire that destroyed the rapper's Long Island, New York mansion where she and 50's son resided. The destroyed home was at the center of recent baby-mama involving the rap star and Tompkins.

After an ongoing child support battle with Tompkins, 50 appeared before a judge in May and requested that Tompkins and their son be removed from the rapper's Long Island, New York, home. The rapper claimed Tompkins was given ample opportunity to find another residence, but made no attempt to relocate from his Dix Hills mansion.

Now, 50's ex claims the rapper set fire to the home in an attempt to force her out of the mansion. Tompkins' attorney Paul Catsandonis is trying to make the case that the pair's relationship can be viewed as a common-law marriage.

"There wasn't a written contract but an expressed oral agreement, which is recognized in the New York courts," Catsandonis said in a recent interview. "They decided years ago that she was going to be the domestic partner, and she was going to provide the domestic services while he devoted all his time to becoming a Hip-Hop artist. Whatever profits he was able to achieve would be divided equally, and he had promised her and their son that they could live in the house. He breached that contract."

I guess we'll have to wait and see if Tompkins will get rich or die tryin.'
