Rapper 50 Cent has spoken out about his rocky relationship with his ex-girlfriend - claiming she is using their son in a bid to hurt him.

The hip-hop star and his former lover Shaniqua Tompkins have been battling in court over 50 Cent's Long Island, New York home, where Tompkins and 11-year-old Marquise have been living. The house was destroyed by fire in May.

The rapper is currently suing Tompkins for defamation after she accused him of starting the blaze.

Last week, Tomkins was granted a restraining order against the star, real name Curtis Jackson, which would prevent him from being on the same premises as her.

And now, Jackson has posted a video of his thoughts on the mother of his son on his website ThisIs50.com, claiming Tompkins is angry because he cut her child support - meaning she couldn't live the life of luxury she had become accustomed to.

In the video he says, "It's a huge adjustment when you have a person who has a sense of entitlement because she was around during that time period when I didn't have much. She feels like she should be entitled to the world."

"She's really having a bigger adjustment to her personal lifestyle because she has a bag habit that costs more than the child support."
