Christina Aguilera And Adam Levine At War On ‘The Voice?’

The Voice coaches Christina Aguilera and Adam Levine clashed over Tony Lucca’s solo performance on the finals Monday, a rock version of Jay-Z’s “99 Problems.”

Lucca decided to mute out the b-word in the song’s hook: “I’ve got 99 problems but a mmm ain’t one,” he sang.

Calling attention to Lucca’s wife and daughter in the audience, Aguilera, 31, told Lucca she believed “the lyrical connotation was a little derogatory towards women, but all in all I thought it was fun.”

Lucca’s Voice mentor, Adam Levine, then stepped in to defend the singer. “We’re not referring to women, we’re referring to everything…it’s called a metaphor,” he told Aguilera. Watch the exchange after the jump.

Levine then told Aguilera, “I love you Christina,” and ripped off his plaid shirt to reveal a T-shirt with pink sparkles that read, “Team XTina.” 

Speaking to Us Weekly backstage after Monday’s show, Lucca couldn’t believe Aguilera’s behavior — and was miffed that he dragged his wife and daughter into her critique. “How convenient that she waits the whole season to talk about all things classy,” Lucca sniped of Aguilera. “It’s just so transparent at this point and pathetic.” reported that earlier in the day things got way out of control. The gossip site also says Adam “blew up” at Christina when the coaches rehearsed “Free Your Mind,” calling her “the biggest f***ing ****.” They had sparred earlier over Tony Lucca’s Adam Levine-inspired choice of Jay Z’s “99 Problems” for his final solo performance.

The source says an “immature” Levine then locked himself in his trailer after the blow up, delaying production. “Christina is so sick of Adam being looked at as the golden boy of the show,” the spy tells RadarOnline. “If America knew how disgusting he was, they would be appalled, she always says.”

The season finale of The Voice airs tonight at 8 p.m. Eastern time on NBC.
