To those of you who may be contemplating working with a celebrity, make sure that Rihanna sure as hell isn't one of them. Why, you ask? Simply put, the broad may 'jip' your ass in the process.

This time, her willingness to exercise foul business practices has gotten her ass in the middle of a damn lawsuit.

The singer has not paid her personal trainer, Cindy Percival, roughly the $30K she owes for keeping her in shape or excellent physical condition. Yes, that's right nay sayers, Rih Rih had a trainer to keep that fine ass body of hers tight!

Unfortunately, if she doesn't come up with the payment for services soon, Percival may feel compelled to Chris Brown her *kidding*. Would it be just due? According to some, possibly.

A fit piece of advice to the Rihannamites of the world, it is only fair practice to pay for services rendered. There is no blessing in jeopardizing a man's livelihood for the sake of motherfucking vanity.

Oh and by the way, for you Illuminati theorists/experts, she will be featured in a DVD called 'The Demonic Possession of Jay - Z and Rihanna'.
