The annual ceremony is under threat of cancellation after celebrities from the music industry pledged their allegiance to the Writers Guild of America (WGA) union members.
Prince, Alicia Keys, Fantasia, Nelly Furtado, Tim McGraw, Kelly Clarkson, the White Stripes, Fergie and Usher are also threatening to boycott the event, scheduled to take place in Los Angeles on Feb. 10, reports the New York Daily News.
A source tells the publication, "The writers are especially interested in artists who might perform on the show. If they pull out, the show comes apart."
But a spokesman for the WGA says, "As of now, the Guild has not taken a position on the Grammys."
