T.I. got busted at his own gated community in Georgia after he got into it with a security guard for the neighborhood.
According to local reports, the rapper was trying to get to his house Wednesday morning -- around 4 AM -- but didn't have his key. T.I. and a friend argued with the guard at the security shack, who wouldn't let them enter ... and it got heated enough that cops showed up.
Henry County PD arrested Tip for simple assault, disorderly conduct and public drunkenness. He certainly doesn't look too pissed in his mug shot.
He's already been released ... without bail.
