Selena Gomez Sings Britney Spears at SXSW – And Britney Responds [VIDEO]
During Selena Gomez's appearance at SXSW yesterday (March 11) to promote the upcoming film 'Spring Breakers,' she and her castmates broke into an impromptu performance of '...Baby One More Time.'
A performance, we should say, that was buzzworthy enough to get even Britney Spears' attention.
