Christina Aguilera disses Lady Gaga

Christina Aguilera can’t keep her feelings to herself.

The pop diva apparently stunned onlookers by launching a foul-mouthed tirade against pop rival Lady GaGa.

Aguilera was said to be unable to hide feelings during a recent taping of The Voice and began blatantly bragging about how much more enter­taining she is than GaGa.

“Christina told a contestant she was 10 times better than GaGa, said her rival was annoying and expressed her amazement that Gaga ever got famous,” a source said.

“It caused quite a scene, and producers insisted on reshoot­ing the segment.”

Aguilera has previously insisted she isn’t at war with the Poker Face hitmaker.

“I have absolutely nothing against Lady GaGa or any other female artist in this business,” she

“I think she is great, and I appreciate any woman fearless enough to go against the norm. She has earned her success with hard work and a clear focus and I have nothing but respect for that. There is room for all of us on everyone’s iPods.”

“This is not the first time I have been unfairly pitted against another female artist,” adds the one-time rival of Britney Spears, “but it will be the last time I comment on the matter.”
