CHRISTINA Aguilera fired from The Voice?

NBC has slammed reports CHRISTINA Aguilera to be axed from The Voice.

"There is absolutely no truth to the rumor," Paul Telegdy, NBC Executive Vice President, Alternative Programming, said in an official statement.

According to reports Aguilera has already signed up for a second series of the show, but producers are said to be unhappy with her on the show and want to replace her.

"She doesn't spent time with her contestants like she's supposed to," a source said.

"She doesn't participate. She spends most of her time on the set with her boyfriend."
