Adam Levine thinks Christina Aguilera’s weight is “no one’s business”. The singer told Us Weekly that he has Christina’s back and defends her, especially from bullies, who “feel like they can just say nasty things about other people.”

Adam Levine: Aguilera’s weight is no one’s businessIn a recent interview for Us Weekly Adam Levine jumped into Christina Aguilera’s defense when it came to her body size. The Maroon 5 frontman believes those who criticize a celebrity for her weight or any other dimension of that celebrity’s look, should “grow up”.

The “One More Night” singer called Aguilera’s critics bullies and added: “She gets a lot and it pisses me off. Of course I have her back and of course I defend her.”

This may sound awkward for those who watch “The Voice”, as during the show, the two fight a lot. Their behavior started rumors that they might actually have a feud behind the scenes. But Levine says no. “We never hated each other”, he said, adding that all the fights thought to have taken place between them are “fictional”.
