Gay pop star Elton John has accepted an invitation from homophobic rapper Eminem to perform in a duet at next week's Grammy Awards. "I'm a big fan of his music, and I said I would be delighted to," John told the Los Angeles Times. "I know I'm going to get a lot of flak from various people who are going to picket the show... [but] if I thought for one minute that he was [hateful], I wouldn't do it." The Gay &#038 Lesbian Alliance Against Defamation (GLAAD) — which is planning a pre-Awards show protest — called John's decision "hurtful" and "embarrassing." The duo reportedly will perform Eminem's "Stan." Meanwhile, in an interview with BBC Radio One, the controversial artist said that he may soon make his big screen debut. "There is an offer that came across recently that does sound appealing to me," he said. "It is an action movie. That is all I can say. I would be the villain. This is the first offer I have got that actually sounded appealing to me."
