By now, it’s no secret 50 Cent and Ja Rule have been embroiled in a long-running feud. Anytime the Murder Inc. vet finds himself in any kind of controversy, Fiddy is usually one of the first to insult him in some way.

Today is no different. After reports began circulating about Ja Rule’s IRS troubles on Monday (April 15), the Power executive jumped right on it. 50 took to Instagram on Tuesday (April 16) to mock Ja Rule for reportedly owing roughly $2 million in back federal taxes.

“LOL come on,” he captioned the photo. “I know he not that bright but damn. #lecheminduroi #bransoncognac #bellator.”

According to Bossip, Ja Rule owes over $2 million in back federal taxes on liens stretching back more than a decade.

But this isn’t the first time he’s faced issues with Uncle Sam. In 2011, a judge sentenced the seasoned artist to 28 months in federal prison after he pled guilty to tax evasion. Public records state Ja Rule hadn’t responded to the latest liens as of Monday (April 15).
