Sarah Harding feels lucky to have been given the chance to act.
The Girls Aloud star, who plays the role of schoolgirl Roxy in 'St Trinian's 2: The Legend of Fritton's Gold', says she is living out her dream on the big screen.
Speaking at the world premiere of the movie In London's Leicester Square, Sarah told BANG Showbiz: "I'm just enjoying every minute of it at the moment. I'm getting to live out my fantasies.
"I've lived out my dream doing the singing and I never thought I'd get into doing the acting side of it as well, which is amazing. I'm very honored and grateful that they are giving me a chance."
The 28-year-old star, who braved the cold on a special pink carpet in a stunning cut-out dress, also denied there was any competition between Girls Aloud as each member focuses on individual projects.
She said: "We've all got very different tastes and I think if were to all do our own solo stuff it would be very different."
Sarah also admitted she loved working with her co-star Rupert Everett, who has to dress as a woman for his role as school headmistress Miss Fritton.
Sarah said: "Rupert's boobs kept falling down. He was just hilarious. We couldn't take him seriously. It was just a giggle every day."
Fellow Girls Aloud band members Nicola Roberts and Kimberley Walsh attended the premiere to support Sarah, while her co-stars Gemma Arterton, Rupert and Tamsin Egerton also attended.
