It seems that everything about Eminem's new single is rooted in controversy... even its release date.

Em's "The Real Slim Shady" (which slams Christina Aguilera, Fred Durst, and Carson Daly, among others) arrived at radio earlier than expected after the track turned up online via controversial Internet music distributor Napster.

The track is the lead single from Em's upcoming "The Marshall Mathers LP," and while the album was just mixed on Thursday, the single had already hit Napster by last weekend.

In response to the leak, Em's label, Interscope Records, shipped the song to radio one week sooner than expected. "The Marshall Mathers LP" is still slated to hit stores on May 23.

A source told MTV News that it was "a miracle" that the single stayed under wraps this long, considering the controversy over Eminem's profanity-laced and sexually suggestive rap that targets boy bands and other teen pop icons.

As we previously reported, Em's track

reserves a few stinging lines for Christina Aguilera (see [article id="1424811"]"Aguilera Responds To Alleged Eminem Dis"[/article]). With Em's dis of the singer hitting radio outlets around the country, Aguilera's camp stands by its original statement calling Eminem's lyrics "disgusting.

Meanwhile, Carson Daly (who is also among the many celebrities slammed in the song) told MTV News Thursday that he didn't mind, and added, "I think the song will be a big hit.

Fred Durst is also skewered on the single, and a label spokesperson for the Limp Bizkit frontman had no comment on the song and noted that Durst will appear in the video for "The Real Slim Shady.

Eminem plays a number of characters in the clip for the song, which concerns the search for "The Real Slim Shady," and he says the shoot was a success.

I'm excited for once about a video," Em said after wrapping the shoot. "I'm feeling this video. I'm having fun with it.
