Christina Aguilera will host the Radio Music Awards in Las Vegas on Friday at the Aladdin Casino in Las Vegas (though no mention of her on ABC’s official RMA site has some wondering about a last minute cancellation). Among the guests at the show will be Mariah Carey, Jessica Simpson, *NSYNC’s Lance Bass & Joey Fatone, Christina Milian, Nelly Furtado, and Elton John, who will receive this year’s Legend Award. Christina said of the opportunity to host, “It is kind of a different thing for me because I’m speaking my way through it. I’m not performing. But it’ll be a fun night just because God knows what’s going to happen.” Check out the show on October 26 at 9 PM on ABC.
