Cressida Bonas in Trinity show resurfaced online

Cressida Bonas had short cameo in ITV2 drama Trinity, it has emerged today.

Prince Harry’s girlfriend is said to be “mortified” after brief footage of her as a cheerleader in the short-lived TV drama resurfaced online.

Cressida Bonas, 24, appeared in just two minutes of the canned Trinity series wearing a cheerleader costume. She is among a group of girls who offer s***al favors in order to win votes on the student council in the clip.

Trinity, which appeared on ITV2 in 2009, centred on the fiction school Trinity College and was filmed in Royal Holloway, University of London.

Cressida Bonas got the job through her half-sister Isabella Calthorpe, who also features in the series and was said to be the object of Prince William’s affection after he and Kate Middleton broke up in 2007.

According to the Sun, a source said: “Cressida will be mortified – she had been hoping this acting gig would never see the light of day.”

Cressida Bonas’ character is one of a group of girls who enters a bedroom full of male students holding a maths and computer science party.

Isabella Calthorpe’s characters asks: “We were wondering if you handsome young mathmos had decided who to vote for in the student rep elections? And to help you decide we thought maybe you’d like to party? Come on girls.”

Trinity was cancelled after one season because of low viewer ratings.
