Christina Aguliera and Adam Levine got into a nasty fight during last night’s rehearsal on The Voice and it rolled on over into the live show.

Adam took a stab at Christina through his finalist’s song choice. He told Tony Luca to sing ’I’ve got 99 problems but a (b) ain’t one’ and to aim the song at Christina. Adam wanted Tony to call out Christina for being a major b, but also let her know that she won’t stand in his way. Remember, Christina snubbed Tony from the very beginning. She didn’t remember him from back in the Mickey Mouse club days and she’s turned her nose up at his performances.

Christina was highly offended and demanded that they change the word to ‘chick’. Adam blew up at Christina, threw all kind of highly offensive swear words at her. He stormed off the set and Christina demanded that he get fired. She said that she’s so sick of him being looked at as the ‘golden boy’ and America would be disgusted with him if they knew what he was really like.

Well Tony did sing that song for the live show. He didn’t point anything out to Christina but she made a remark after his performance. She said, "I thought you sounded great. I mean, you have a really cool voice... You know, I know your beautiful wife and your daughter and family are here tonight, and I just thought, you know, the lyrical connotation was a little derogatory towards women, you know, but all in all it was good fun." Adam argued that the intent behind the song is life getting at you, not particularly a woman. Then he ripped off his shirt and revealed a sparkly pink ‘Team Xtina shirt’.

Whose side are you on in this catfight?
