Tank: Tyrese Got Greedy ... That's Why TGT Split Up

Tank is putting the blame squarely on Tyrese when it comes to the breakup of their R&B supergroup, TGT.

It's an interesting twist ... Tyrese had announced the group's demise in December, but didn't blame anyone in particular. All he said was the group would be moving on without Ginuwine -- which seemed like a hint, but now Tank's pointing the finger at Tyrese.

Watch what happened at LAX when we asked for a TGT update. For Tank, it's all about the Benjamins.

A rep for Tyrese says the group's money was never split equally because the economic fact is Tyrese has had more chart success on his own. The rep did not deny money was behind the breakup.

On a personal level ... the rep said Tyrese still considers Tank and Ginuwine his brothers, but "business is business."
