Prince Harry's girlfriend Cressida Bonas has been left "mortified" after footage of her on a seedy TV show has emerged.
The 24-year-old beauty - who landed the role through half-sister Isabella Calthorpe, who had a lead role in the drama - starred in one episode of ITV2 programme 'Trinity' in 2009 as one of a group of girls who offer sexual favours to win student council votes.
A source told The Sun newspaper: "Cressida will be mortified -- she had been hoping this acting gig would never see the light of day."
The two minutes of footage, which was in the fourth episode of the eight-part show, sees Cressida dancing in a Superman top which bares her midriff.
The programme, which was based on the fictional Trinity College and filmed at the University of London, was axed after one series when half of its initial 1.2 million viewers ditched the series before the final episode.
Earlier this month, Harry laughed off rumours he plans to pop the question to Cressida, who he has been dating for the past 18 months, at a charity dinner in Dubai.
