T.I. is re-writing the script when it comes to welcome home parties, because the recently-released rapper isn't throwing himself a nightclub bash … he's having a brunch in Atlanta!

Diddy is personally shipping in 150 bottles of Ciroc, one for each person in attendance. We're told the whole bash will cost around $100K, with $20K just on food and additional $8K on dessert.

The big surprise of the night, T.I.'s clothing line AKOO, will measure the VIP guests for custom-made clothing gifts.

It's set to go down on October 2, two days after T.I. gets released from the halfway house.
