Christina Aguilera has a message for folks who've been gossiping about her new-found curves -- they're real and they're spectacular!

Her camp offered that response after Star magazine sniped that X-Tina may have "spent some quality time with a plastic surgeon" to perk up her rear end. The magazine quoted a doctor who's never seen her in person as saying, "It could be likely that she has had lipo-sculpture to the waist and fat injection to the buttocks.”

Gossip Cop went to The Voice, and reports that her compatriots there laughed off the claim, saying "it's obviously not true."
