A different kind of rap feud may be brewing -- as T.I. has taken fellow hip-hop star Lil Wayne to task for recent dismissive remarks he made about the Black Lives Matter movement.

During a recent sit down interview with "Nightline," Lil Wayne appeared to be put off when the activist group was mentioned saying he doesn't feel "connected" to it, that it "ain't got nothing to do with me," before telling the interviewer Linsey Davis: "Don’t come at me with with that dumb a-- sh-t."

Later, the rapper tried to clarify his comments, arguing that he became agitated when he was asked how he'd feel if some of his more salacious and incendiary lyrics were directed at his own daughter.

He also apologized for his comments and reportedly fired his publicists for allowing the interview, which he reportedly walked out of in a huff, to air.

Still, his rhetoric appears to have rubbed chart-topping rapper T.I. the wrong way.

T.I., who has been an outspoken proponent of the Black Lives Matter movement and has recently released an EP ("Us or Else") of socially conscious hip-hop which touches on some of the organization's themes of police brutality, called out Lil Wayne in an open letter published on Instagram this past weekend.

“I don’t know what you goin thru, or what you are attempting to avoid but this sh-t is absolutely unacceptable!!!!,” T.I. wrote. “You’re disrespecting yourself, bringing shame on your family name & tarnishing your legacy. … If you’re not prepared for a question in an interview, say No Comment Bro. But stop embarrassing yourself & everyone out here who’s been supporting you. There is no middle ground. Oppression knows no neutral party, either you’re part of the oppressed, or you with the oppressor.”

"YOURE BETTER THAN THIS!!!!! I've been proud to call myself a fan & a friend of Lil Wayne ,but if that must end in order to stand up for those who can't do it for themselves...So be it," he added.

Meanwhile, this is not the first time a Lil Wayne statement or lyric has run afoul of other members of the black community. In 2013, he created considerable controversy when he made a crude reference to the death of Emmett Till on the track "Karate Chop (Remix)," and this September he told Fox Sports' Skip Bayless he felt detached from NFL quarterback Colin Kaepernick's polarizing silent protests during the National Anthem.

"I'm not into it enough to even give an opinion," he said.

Lil Wayne also claimed he'd "never dealt with racism" in his life.
