London, July 12 (ANI): Girls Aloud singer Sarah Harding is set to star in the sequel of the film St Trinian’s.

She was spotted on the sets of the film in a variety of skimpy schoolgirl outfits, hot pants, chunky biker boots or sandals, according to shot changes.

The new film, St Trinian’s 2: The Legend Of Fritton’s Gold, will also star David -Tennant, who plays the villain Pomfrey, member of a secret woman-hating society known as AD1.

The story revolves around sexy pupils on the hunt for buried treasure, after they discover that headmistress Miss Fritton, reprised by Rupert ­Everett, is related to pirates.

“It’s a girls’ heist movie and how many times have you seen that? But it just clicks with girls, who ­enjoy the naughtiness and fun.” the Daily Express quoted co-director Barnaby Thompson as saying.

Harding had a cameo part along with her Girls Aloud bandmates in the previous film.

The last movie in a long-running series of films had amassed 15 million-pound at UK box office in 2007. (ANI)
