Rapper Tip "T.I." Harris legally lashed out at the woman who alleges he put a gun to her head and threatened to kill her.

Sabrina Peterson is suing T.I. and his wife Tameka "Tiny" Harris for defamation, but in new legal documnents obtained by TMZ, T.I. is asking a judge to throw her defamation lawsuit out of court.

T.I. claims Peterson's reputation is already so scandalous, that it's impossible to harm her reputation any further.

As TMZ reported, in her lawsuit filed earlier this year, Peterson claims T.I. and Tiny smeared her good name with public statements and social media posts.

However, the rapper's lawyer, Andrew Brettler, claims Peterson "is an adjudged liar, a convicted felon with a lengthy rap sheet for crimes involving dishonesty and violent assault, and has a reputation for being unscrupulous."

Additionally Brettler says there's no way T.I. and Tiny could besmirch Peterson's already sullied reputation.

According to Peterson's lawsuit, Tiny referred to Peterson on social media as "strange," and added, "everybody know you been special."

Peterson claims she has since become the target of online harassment and threatening messages, but T.I. claims she can't sue over those comments because they are just opinions.

T.I. retained Brettler because he is admitted to try cases in California, where Peterson lives. T.I.'s longtime attorney, Atlanta-based Steven Sadow, is only licensed to practice law in Georgia.

Defamation, also known as slander, is more difficult to prove because it is usually uttered as an opinion.
