Adam Levine, Lady Gaga Face Off in Twitter War Over 'Art'

Maroon 5 front man Adam Levine and Lady Gaga are feuding on Twitter after the rocker took a virtual swing at the pop star last week.

Levine seemingly called out Gaga Friday in a series of tweets.

Ugh..recycling old art for a younger generation doesn't make you an artist. It makes you an art teacher.

— Adam Levine (@adamlevine) September 20, 2013

I unabashedly love writing and performing pop music for both myself AND everyone around me. That's It. It doesn't need any extra sauce.

She quickly snapped back:

uh oh guys the art police is here

— Lady Gaga (@ladygaga) September 21, 2013

Levine's comments appear to be a criticism of Lady Gaga's upcoming album "ARTPOP" and her new music video for her single "Applause." The video features famous works of art, including the 1957 film "The Seventh Seal" and Sandro Botticelli's 1486 painting, "The Birth of Venus," according to E! Online.

"'Applause' is a very meaningful song to me, because it addresses what many think of 'celebrities' today, that we 'do it' for the attention," Gaga tweeted Sept. 18. "But some of us are 'artists' in this group called 'celebrity,' & what we create doesn't live on unless theres [sic] an audience to remember it. So I may need your attention at first, so I can sing you my song. But it's the 'Applause' after that let me know if I've entertained you."

The Twitter war started back up again Tuesday.

by the way, im NOT an artist. i sing in a band and i make music with my friends.

while we're at it we should call the grammar police.

— Adam Levine (@adamlevine) September 24, 2013

"The Voice" coach's "grammar police" comment was a dig at Gaga's earlier tweet where she mistakenly used "is" instead of "are."

The pop star has yet to respond to the latest round of taunts.
