Katy Perry unaware of GMTV show live broadcast

Singer Katy Perry was left red-faced at the Oscars after her boyfriend Russell Brand chastised her on live TV for swearing. The ‘I Kissed A Girl’ hitmaker blurted out an expletive on the red carpet as she left the Academy Awards ceremony in Los Angeles Sunday night, reports contactmusic.com. Perry, however, says she was unaware the late-night interview for British show GMTV was being broadcast live.
