The Saturdays never discuss getting back together when they see one another

She said: "I hope there will be [a reunion].

"I'd certainly like to be part of it and hope it would be all five of us.

"I don't know how the others feel because we never bring it up.

"We chat about everything else, but it's a bit of a taboo subject for us because it's not on the cards.

"Everyone is busy doing something else and It requires commitment from everyone and I don't think everyone is ready for that just yet."

But the 36-year-old singer - who has children Aoife, six, and Tadhg, three, with husband Ben Foden - doesn't get to see the rest of the band very often these days.

Una explained that because she doesn't live near to any of the other girls, it's become increasingly difficult for them to get together.

She said to New! magazine: "I'm living in Northampton and I haven't seen them in a while now. But when we do see each other, it's like we've never been apart."

The 'Never See Me Cry' singer also insists she doesn't feel pressure to do better than her bandmates in her solo efforts and there's no competitiveness between them.

Asked if she feels under pressure to be most successful, Una said: "Absolutely not! People almost put you under pressure when they ask that.

"[Are we in competition?] No, we're five individuals who support each other."
