Eminem & Rihanna 'The Monster' Tour, 'MMLP2' rapper demands Drake's girlfriend to 'sober up' before hitting the road in August, no lip-syncing?

It's no secret that rapper Eminem struggled with a severe drug abuse problem in the past. But those days are long and gone, and the infamous Detroit emcee is ready to take the hip-hop world by storm again. Slim Shady will hit the road this August alongside Rihanna for the highly-anticipated "The Monster" Tour. But will RiRi's hard-partying, drinking ways ruin everything?

According to the shady gossip tabloid Star, yes.

According to the magazine, the MMLP2 rapper "told the party-loving singer to stay on the straight and narrow." He's five years sober now, and doesn't want to be around that sort of environment. He's all about being healthy while touring:

Eminem tour demands: German pickles, yogurt, peanut butter, jumbo shrimp, Swiss mild cheddar cheese, NO drugs or alcohol, 'MMLP2' rapper 'totally clean' in 2014

An alleged insider explains:

"Rihanna has been pushing Eminem to tour together for a while now. He finally gave in - as long as she stays sober, acts professional and doesn't lip-sync! If she's unprofessional in any way, he's done."

I'ts great that Shady wants to offer his fans the best live show possible, but it's hard to believe he'd speak to RiRi in this way.

Eminem and Drake's main squeeze have been collaborating for years. They work great together, and their different lifestyles have never gotten in the way of their professional and musical success:

A rep for Gossip Cop confirms that this story is "completely made up."

So, how many fans plan on hitting up "The Monster" Tour this year?
