The ongoing feud between The Voice's Christina Aguilera and Tony Lucca heated up during Monday's final performance show -- and it wasn't pretty.
Having snubbed Lucca, 36, early on in the competition by failing to recognize him from their Mickey Mouse Club days, and then calling his performances "one dimensional," Aguilera continued to slam the singer on Monday's show.
Covering Jay-Z's "99 Problems," Lucca avoided the word "bitch" in the lyrics of the hip-hop hit, but Aguilera was still unimpressed and declared the routine "derogatory towards women."
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.
Later, Aguilera -- who spent the duration of Lucca and Levine's duet performance texting on her phone -- took another dig at Lucca, comparing him to "real man" Chris Mann.
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."
Lucca will face off against Jermaine Paul, Juliet Simms and Chris Mann for this season's title and a recording contract Tuesday.
