T.I. -- Iggy Azalea Ain't My Problem Now

There's only so much T.I. can do -- the rapper and music mogul has cut ties with Iggy Azalea after standing up for her time and time again.

T.I. went on Ebro in the Morning on NYC's Hot 97, and said there were no hard feelings now that their biz relationship is over. He even stood up for her one last time, saying ... "She had a lot thrown at her at one time. It's very difficult to be the new kid and to be the butt of the jokes."

T.I. had been managing Iggy's music career, but in the last year has seemed more like a bodyguard -- defending her every time she had beef with other celebs like ... Snoop Dogg, Q-Tip, Britney Spears, Nicki Minaj, Eminem, and Azealia Banks.

We kinda saw the wheels coming off back in January when we asked Tip about Iggy's feud-of-the-moment with shoe mogul Steve Madden.
