All is not well in the Wu-Tang Clan camp. According to TMZ, U-God believes he's been cheated out of some serious revenue over the several years and he is now suing his group for $2.5 million. Ouch.

In legal documents filed in New York, U-God claims that he's helped out with at least 170 Wu-Tang songs since the group was created some 23 years ago. He says it's been six years since he's gotten his percentage of the royalties. Now, he's hitting back.

Apparently, U-God is pointing his finger at RZA and his brother Mitchell Diggs. U-God claims that those two have been using their powers as the founders of the Wu-Tang Clan to keep him away from the money he's rightfully owed. U-God says he's also supposed to receive two payments for Wu-Tang's merchandising revenue every year.

U-God also has a bone to pick over Wu-Tang's latest album, Once Upon a Time in Shaolin has yet to comment. Apparently U-God hasn't received any money from the album, which the infamous Martin Shkreli purchased for $2.5 million.

We really have no clue of where this situation is going from here. But then again, maybe we do.  Disputes over album royalties aren't staples of rock group biopics for no reason. When someone feels they're being cheated out of money--especially by some of their own friends--things can get very, very ugly.
