Una Healy has said her life has been turned "upside down" since her split from husband Ben Foden.
It was announced in July that the couple were going their separate ways after six years of marriage.
Una (36) moved back to her native Tipperary shortly after the split, taking their children Aoife Belle (6) and Tadhg (3) with her.
Speaking for the first time since the split, Una told Hello! magazine: "My life has been turned upside down and I'm trying to figure it out.
"I'm taking each day as it comes and just being there for my children."
It was reported that Foden had cheated on Una with PR girl Becky Milne in London.
Una was reported to have read text messages between the pair and subsequently ended their relationship.
Shortly before the split, the family were planning on moving to the US after Foden landed a contract with Rugby United New York.
Now that she's back at home, former Saturdays singer Una said her main priority for the time being is looking after her children.
"I'm so lucky to have them. I never feel lonely or alone," she said.
"They're lovely company and have brought joy into my life. The most important job for me is to be the best parent I can and to provide for them and look after them. They're my priority.
"You have to be strong for your children as they're dependent on you.
"But with that responsibility comes great satisfaction. I'm looking forward to all the milestones in their lives that we'll share."
Una revealed a new look shortly after announcing the split.
Known for her gorgeous red hair, the mum-of-two underwent a dramatic make-over, showing off a new blonde look.
She was in London yesterday for fashion week and joined the likes of Erin McGregor and former Xpose presenter Ruth O'Neill at Irish designer Paul Costelloe's show.
Una, who has become a solo singer since The Saturdays split up, is feeling positive about the future, saying her family have provided her with a lot of support.
"They've been rallying around when times are tough. I've been sent letters that are really supportive too," she said.
"Life is tough, but you've got to keep a positive attitude. Time is a healer as well."
Foden was reportedly spotted on dating app Bumble shortly after news of the couple's break-up came to light.
