Eminem has drawn crossover support for his controversial debut album, "Slim Shady," which has been lauded by both white and black hip-hop audiences. Now the rapper is beginning to be feted by such Hollywood celebrities as Dustin Hoffman.

The actor even went so far as to jump onstage with Eminem during a recent late night show at the House of Blues in Los Angeles. According to the rapper's publicist, Hoffman attended the first show of the evening with his kids and was so caught up in the flurry of excitement that he went backstage and agreed to participate in the second show. For the gig, Hoffman donned a mummy costume (an image lifted from the "Slim Shady" album cover) and joined Eminem and Dr. Dre during the duo's interpretation of "Nuthin' But a 'G' Thang." With his kids rooting him on, Hoffman danced onstage throughout the number, gradually unwrapping his costume so that he had revealed his true identity by the end of the song. Hoffman is certainly no stranger to the criticism

that Eminem has received for the language and word choice the rapper employs on his "Slim Shady" album. In 1975 the actor was nominated for an Academy Award for his portrayal of licentious comedian Lenny Bruce in the Bob Fosse-directed "Lenny."

Bruce was put on trial and convicted of obscenity charges in New York City in 1964 for his stand-up routine, and eventually overdosed in 1966 at the age of 40. No telling who might turn up at Eminem concerts in the next few weeks, as the rapper is expected to finish a spring U.S. tour on May 30 at the World Cafe in Honolulu, Hawaii.
