Nadine Coyle has cancelled her upcoming tour, apologising to fans and expressing her sadness at the decision to not go through with her scheduled shows.

The 32-year-old former Girls Aloud singer was set to perform a mix of her own solo songs and Girls Aloud hits on the tour, which was set to kick off in Glasgow on May 10 and include dates across Ireland and the UK.

Coyle broke the news to her fans via a statement on her official website, which reads: "I am so sad to say I’m not able to do the tour at this time.

"I am so sorry and really wish things were different but for many reasons it is not meant to be. You deserve the best show possible and with such big venues and very little dates it was becoming impossible to achieve what we had wanted to do.

"Everything is a lesson and this is definitely one for me. Thank you for your continued love and support!!!"

Girls Aloud 

Coyle recently opened up about her experiences in Girls Aloud, which she joined in 2002 on Popstars: The Rivals, saying she was never close with bandmates Cheryl, Sarah Harding, Nicola Roberts and Kimberley Walsh.

"There was always a distance between us.We all had our own dressing rooms and we'd just meet up to go on stage," she told Fabulous magazine.

"I just didn't see them. If it had been toxic or horrendous I don't think I'd have been able to do it. I'd have been like, 'You're all right, I'll find another job, thank you'."
