The Irish popstar announced on Friday (5 August) that she's signed a record deal with Decca Records, after quietly working on her debut album over the last two years.
She revealed via Instagram: "So excited to announce I've signed to @deccarecords the home to so many amazing artists I admire. I can't wait to share my music with you all."
Una, 34, also took part in a Facebook Live chat with The Sun, revealing she was "going back to [her] roots" after starting as a singer-songwriter in her teens.
"It's been nice to take some time away from the spotlight," she said.
"I've enjoyed being at home and being a mum with the kids, chilling out and gathering my inspiration to put this album together. I've been co-writing and the whole album is original music, mostly songs I've worked on at home with the guitar."
She insisted, however, this did NOT mean the end of The Saturdays! "This is not a departure from The Saturdays. We're all working on different things and taking some time out. The band hasn't disbanded whatsoever."
Una said the girls first heard her debut material two years ago when she recorded a demo and let them listen. "They've been aware of it for a long time and I think they always kind of knew I'd go back to doing this kind of music. They've been very supportive."
She's filming the music video for her debut single in the US next week.
We can't wait!
And if you fancy seeing Una on tour, well, you'll just have to wait! She said nothing's set in stone but if you're in County Longford in Ireland on 22 August, you can catch her making a special appearance with her uncle, country star Declan Nerney, at the Marquee in Drumlish.
