Not too long after the successful release of his double-platinum selling album, The Marshall Mathers LP 2, Eminem is reportedly ready to release new music, as a member of his old group D12.

Mark Bass, the co-owner of F.B.T. Studios in Em's native Detroit who has worked with Slim Shady and D12 in the past, said he is currently working on new project by D12, including three selections featuring the self-acclaimed "Rap God."

"Bass, who has started a label called Montunes Media, says he's also been mixing new material by the mercurial funk-pop giant Sly Stone with members of the original Family Stone band, along with new D12 tracks, including three with Eminem," the source said.

D12, which featured Eminem, Proof, Bizarre, Kuniva, Swifty McVay and Mr. Porter, has released two full-length studio albums via Interscope and Shady Records. In 2001, D12 released its debut album, Devil's Night, and in 2004, the crew released its latest album, D12 World.

However, Bizarre won't be in the picture this time, as he announced he was no longer part of the group back in February 2012. "We just had creative differences and decided to go out separate ways," he said. "Well, I decided to go my separate way."

In addition, Proof died in 2006 as a result of fatal gunshots. In 2010, Eminem paid tribute to his close friend with "You're Never Over," a track off his 2010 album Recovery.

"For me, this is the most important song off the record," he said. "It's a dedication to Proof. It is one of those records that I tried ... I had several attempts at making. Every attempt just wasn't good enough. It was one of those things, I tried a bunch of records and it just didn't work. Like, 'This is not good enough, the rhyme's not crazy enough, the beat's not crazy enough,' When I finally got it, I felt like, 'Thank you, thank you, God for just giving me the strength to be able to write this record and make it feel like it does.'"

The "Berzerk" rapper's mini-tour in Australia and Africa is scheduled to kick off on Feb. 15 in Auckland, New Zealand.
