LONDON: 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 hit maker blurted out an expletive on the red carpet of the Academy Awards ceremony on March 7, reports contactmusic.com. Brand was asked about his favourite moment of the evening and jokingly claimed he had seen dwarfs attending the event. A giggling Perry replied, “I call him on his bulls**t” and Brand appeared shocked by Perry’s remark, telling her, “Don’t swear. It’s morning in England.” He appeared to be feeling embarrassed due to her blunder.
