Rapper T.I. and his wife Tiny were hit with a defamation lawsuit by Sabrina Peterson, the longtime family friend who claimed he put a gun to her head in 2009.

Peterson sued Clifford Joseph Harris, Jr., 40, and his wife, Tameka "Tiny” Harris, 45, for using their social media platforms to smear her good name.

According to legal documents obtained by TMZ, Peterson claims she got into an argument with her former friend, T.I., who then put a gun to her head and told her, "B*tch I'll kill you."

After Peterson, 42, went public with the allegations in January, Tameka posted a photo of T.I. posing with Peterson's 8-year-old son.

Peterson claims Tameka exposed her son to "vitriol and danger."

The post, which has since been deleted, sparked rumors that the boy was fathered by T.I.

T.I. and Tiny's high-powered attorney, Steve Sadow, tells TMZ they "deny in the strong possible terms these unsubstantiated and baseless allegations."

Sadow added, "These allegations are nothing more than the continuation of a sordid shakedown campaign that began on social media." He said T.I. and Tiny "implore everyone not to be taken in by these obvious attempts to manipulate the press and misuse the justice system."

In related news, a NY-based attorney sent letters to federal prosecutors in two states asking them to investigate allegations of drugging and sex abuse lodged by at least 11 women.

Attorney Tyrone A. Blackburn told the New York Times that the women were drugged, raped or sexually assaulted by the Harrises or those in their inner circle of friends and associates.
