The legends of rock and pop join the already-extensive bill at the biggest music awards event in the US...

MADONNA and U2 are reported to have confirmed appearances at this year’s GRAMMY awards at LOS ANGELES STAPLES CENTRE on February 21.

And it has also been confirmed that Eminem has also been approached to appear, despite his four nominations provoking outrage and protests from gay, lesbian and women’s groups.

Up to 12 artists will perform at the ceremony, the biggest music awards event in the US, and Madonna has been nominated in three categories, including Best Female Pop Vocalist for ‘Music’ and Record of the Year. In her career she has scooped five Grammys.

U2 are nominated in three categories also, including Song and Record of the Year for ‘Beautiful Day’. Their latest album ‘All That You Can’t Leave Behind’, was released too late to be included for nomination. The awards are to be broadcast on CBS in the States.

According to [url=], a spokesperson for Eminem said he had not yet decided whether he would appear or not, despite being nominated in four categories. Last year, the rapper won two gongs, but didn’t appear at the ceremony and later rapped:“Do you think I give a damn about a Grammy? in ‘The Real Slim Shady’. This year’s nomination announcements were greeted with protest from lesbian, gay and women’s rights groups.

As reported on NME.COM earlier today, the rapper’s lyrics have been linked with the death of a teenager in England last September. The 17-year-old student wrote a suicide note beneath a quote from the song ‘Rock Bottom’.
