Tiny Harris is calling out the excuse being given for taking her husband T.I. back into custody a day after he was released. She says the allegation that he did not tell them he was being transported in a luxury bus is bulls**t. Especially since some of the prison staff took pictures with Tip in front of the bus and no one said there was a problem.

T.I.’s wife tells TMZ … multiple prison officials actually saw the tour bus that picked up the rapper yesterday — and even took photos with T.I. in front of it — and NOBODY raised an issue.

Tameka “Tiny” Cottle tells us … when the tour bus rolled up to the Arkansas prison yesterday, prison officials, “Walked him over, took pics and told him good luck in life.”

TMZ broke the story … the warden ordered T.I. back into custody after he made the trek to his halfway house, claiming T.I. only informed officials he would be traveling in a van … and not a tricked out tour bus.

But Tiny says, “This is a bunch of bulls**t … they should have said something before he got on the bus … T.I. would have politely gotten into a van.”

She adds, “T.I. is one of the strongest individuals I know … and they just trying to break him in more ways than one and it’s not gonna work! ‘Cause what God got for him, can’t no man take that away … period!”
