Sarah Harding attends premiere of her first major film
Taking place last night in London's Leicester Square, Nicola Roberts and Kimberley Walsh from the girl group joined "nervous" Sarah on the pink carpet for the screening.
Speaking about her move from singing to acting, Sarah said: "I'm nervous about everyone out there, and the critics seeing it, more than anything - it's a really, really great amount of pressure."
She added that, although she had trained for acting when she was younger, she felt people did not expect her to cross over into acting.
Her co-stars Venus actress Jodie Whittaker, Rupert Everett and Celia Imrie also attended the premiere.
Along with the other members of Girls Aloud, Sarah made a brief cameo in the first St Trinian's film as a member of the school band and also had a small part in independent British film Bad Day.
