After months of being tightlipped about his highly anticipated Relapse album, Eminem recently revealed some details about his long awaited opus.

Last month, Swizz Beatz claimed that he had produced 5 songs on the Relapse album. One of the songs that Swizz said he had produced was a sequel to Eminem's 2000 hit "Stan".

"Stan", which was featured on Eminem’s second album The Marshall Mathers LP, told the story of a fan obsessed with the rapper who commits suicide.

In a recent interview with Billboard, Eminem shot down Swizz's claims and stressed that he hasn't collaborated with the famed producer.

"There isn't a 'Stan 2,' and there won't be," Eminem said. "Stan drove his car off a bridge and I'm not writing a song as Stan's ghost. That would just be really corny."

One producer that Eminem is definitely working with is Dr. Dre.  Em divulged that Dre's platinum touch will be all over his eagerly awaited album.

"Me and Dre are back in the lab like the old days, man," Eminem explained. "Just him banging away on tracks and me getting that little spark that makes me write to it. I don't have chemistry like that with anyone else as far as producers go -- not even close. Dre will end up producing the majority of the tracks on Relapse.' We are up to our old mischievous ways ... let's just leave it at that."

Eminem also spoke on a song from Relapse that was leaked last week. The song, which was titled "Number One" by various mixtape DJ's, featured Eminem rapping as Dr. Dre. [Listen to 'Number One']

According to Eminem, the leaked song was far from complete and it's real title is "Crack a Bottle".

The Detroit rapper revealed that he was doing guide vocals for Dre and the song fell into the wrong hands. Despite the leak, the song will still be appearing on Relapse.

"It wasn't close to finished. [It was] me doing guide vocals for Dre as a suggestion of how he could lay his verses down," Eminem said. "It's like someone catches you peeping in your window before you got the Spider Man costume all zipped up! Nobody is supposed to see that. We are gonna finish it up though and get it out there how it's supposed to be."

Eminem expects to have Relapse in stores next spring. He also revealed 50 Cent will be releasing  Before I Self Destruct in February.
