Lady GaGa refuses to duet at Brits?

Lady GaGa has reportedly refused to perform a duet at the Brits. The 'Bad Romance' singer teamed up with Elton John for her performance at the Grammys, while at last year's Brit Awards she appeared alongside the Pet Shop Boys. However, the News of the World claims that the star now feels she deserves a performance to herself. "GaGa knows this is going to be her night and she can call the shots," a source said. "She did a duet with the Pet Shop Boys last year but feels she's come far enough to justify getting the stage to herself." Previous reports have suggested that Beyoncé will join GaGa during her performance. Source: DigitalSpy
