Girls Aloud star Nadine Coyle has disappointed fans by pulling out of a reality TV show because the programme's bosses refused to let her undertake charity work.

Nadine, along with fellow members Kimberley Walsh, Cheryl Cole, Nicola Roberts and Sarah Harding, had been lined up to star in new series Passions, which would see TV crews follow the girls around as they embarked upon the "activity of their dreams".

But Nadine was unimpressed when her plan to help underprivileged children in South America was shelved, with the show's producers suggesting she learned how to conduct an orchestra instead.

She said: "I'm not really into reality things or things that aren't to promote Girls Aloud. I wanted to do something with a charity in Bolivia that got kids off the street, but it didn't sit with the programme."

A spokesperson for ITV said: "We are fortunate that four members of Girls Aloud are able to take part and fulfil their passions. It's just a shame Nadine wasn't available."
