Girls Aloud singer Nadine Coyle has reportedly pulled out of a ITV reality show about the group.

The Irish singer has left TV bosses disappointed after she decided not to take part in the show which follows the girls as they take up the activity of their dreams.

“It’s a real shame,” an insider told the Daily Mirror. “The show doesn’t really work without all five.”

The 22-year-old added: “I’m not really into reality things or things that aren’t to promote Girls Aloud.”

She was supposed to be learning how to be an orchestra conductor for the show, but instead wanted to do something for charity.

“I wanted to do something with a charity in Bolivia that got kids off the street, but it didn’t sit with the programme,” she said.

An ITV2 spokesman said: “We are fortunate that four members of Girls Aloud are able to take part and fulfil their passions.

“It’s just a shame that Nadine wasn’t available.”
