Eminem has officially announced Relapse as the title of his sixth studio album. He also premiered a new track, “I’m Having a Relapse,” Wednesday on his Shade 45 channel on SIRIUS Satellite Radio.

While no release date has been set, the LP is expected to arrive before the end of the year. During an interview on Shade 45, 50 Cent hinted that Relapse may even arrive prior to his own new album, Before I Self Destruct, which is scheduled for December 9th.

Eminem celebrated the release of his new book The Way I Am with a party in New York last night that drew the likes of 50 Cent and LL Cool J.
