Adam Levine and Lady Gaga Fued on Twitter?

Adam Levine and Lady Gaga engaged in a Twitter fight on September 20, Pop Crush reported.

The Maroon 5 frontman took to Twitter and aired out his grievances over artists he felt were contrived. There was little doubt that he was speaking of the 26-year-old Applause hitmaker. Lady Gaga has often been accused of being Madonna lite and appropriating ideas as her own.

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

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. — Adam Levine (@adamlevine) September 21, 2013

Lady Gaga responded on Twitter to the apparent diss.

Levine did not respond to Gaga’s tweets nor has he explained why he sent his original missives in the first place. However, Levine is friends with The Voice co-star, Christina Aguilera. Aguilera and Lady Gaga have feuded in the past.
