The Irish songstress took to Twitter today to let her fans know she is working on solo material since parting ways with Cheryl Cole, Kimberley Walsh, Nicola Roberts and Sarah Harding after the end of their 'Ten' tour.

Coyle wrote to her followers: "Back in the studio. If you could hear what i hear!!!! Xxx this is for all of you. Xciting! Xxx (sic)."

After Girls Aloud revealed they were going their separate ways after the end of their tour last month, Coyle caused a stir after writing on the social networking site: "You should know by now I had no part in any of this split business. I couldn't stop them. I had the best time & want to keep going. Xxxx (sic)."

Bandmate Harding spoke out on Coyle's tweet, telling British magazine Look: "I was unaware she even felt like that. At no point did she try and stop us, so you’d have to ask her why she did that. I have to respect her decision."

The ladies' final show took place in Liverpool yesterday and following the end of their set, a tweet was shared via Girls Aloud's official Twitter page that announced the end of the pop group:

"It has far exceeded any of our dreams and we hope we are forever your inspiration and reminder that dreams really do glitter!!"

"Your love and support will stay with us forever but we have now come to the end of our incredible time together."

Today, member Nadine Coyle told her own fans that splitting up wasn't what she wanted and she tried to stop the other singers from making such a definite decision: "You should know by now I had no part in any of this split business. I couldn't stop them. I had the best time & want to keep going. Xxxx"

Speaking to The Guardian this weekend, their former manager said: 'There was a girl in Ireland called Nadine Coyle, and I said, go for this show. She is an amazing vocalist. A real, real singer. So I pushed her in the band, and I said Nadine is the lead singer."

'From then on, there were problems. "I never worked with them very well 'cos they kind of scared me, the five girls together. Five girls! Five girls is a bit scary.

"They were all a bit scary. Generally, girls don't like each other. That's the problem. I couldn't help them with their hair, makeup, all those things. And from the moment I said Nadine was the best singer, the others alienated me.

"Well, she is the best singer! By a mile. But she didn't marry a footballer. If she'd married a footballer she'd have been a big star."

When Cheryl Cole joined the X Factor panel of judges, the tension continued. Walsh said:

"Cheryl knows how to work it. Cheryl is all about Cheryl."

The Irish vocalist will now go by the moniker Nadine 2.0 and has revealed to The Sun newspaper that she's focusing more on her songwriting, and is even working with Celine Dion on a "project" at the moment:

"I'm working on a Celine Dion project – her comeback. Her people contacted my people and now I'm doing that. And I wrote another song for my album with a great producer and he contacted me saying Aretha Franklin wanted to try my song."

"It's amazing to me that songwriting is an actual job."

Watch her performance of 'Insatiable', which was her debut solo single, from The Paul O'Grady Show below:

The 'Insatiable' singer spoke to internet radio host Dean Kelly about the changes in her career, but couldn't help talking about Girls Aloud and revealed:

"We always discuss a ten-year reunion of some sort so we're going to do that, next year! We're definitely going to do something. But it's a whole huge production. Girls Aloud is not just us five, there's like us five plus a ridiculous team of 50 who travel with us, it's amazing."
