The rap mogul became involved in a heated exchange on Instagram after sharing a video of himself and his 15-year-old daughter Deyjah.
In the clip, an embarrassed Deyjah is seen covering her face while T.I. sings Stevie Wonder”s classic hit Isn”t She Lovely.
But a fan clearly crossed the line with the No Mediocre rapper when he posted the comment: “I would crack dat jawnt. [sic]”
A clearly irate T.I. was quick to respond to the troll, warning him against talking about his family.
He wrote: “You & your 623 followers”ll get wiped the f*** out plying wit me bout mines. Try me. [sic]”
T.I. – real name Clifford Harris – spent six months in prison after he was found to be in possession of a huge arsenal of guns in 2007.
The rapper is also being sued for allegedly missing a scheduled performance at a high school graduation party.
