Former Westlife star Kian has recorded the duet with The Big Reunion's Jodi for his debut solo album Home, and yesterday they treated fans to a sneak preview.
The song is called 'I'll Run To You' and the couple joked about how it came about during an interview with Terry Wogan on Radio 2.
Jodi, who recently reformed with Girl Thing, said: "Really, we never thought about singing together at all. A lot of people would ask us and we'd be like, 'No, we won't be doing that.'"
Kian then interrupted: "We won't be that cheesy...now we are!"
Jodi added: "He just sprung it on me last minute! He said, 'The album's nearly finished, it needs to be finished in three days, I need you to go into the studio on Friday!' I was like, 'Huh?!'"
The couple then performed the duet, which can be heard below, live on the radio for listeners.
It's been a busy time for Kian and Jodi lately. While Kian has been in the studio following his I'm A Celebrity...Get me Out Of Here! win in November, Jodi has thrown herself into The Big Reunion.
They have also done presenting work for Daybreak and, for the first time ever, Jodi and Kian have hired a nanny for their son Koa, who turned two in December.
Kian said: "It's been such an amazing few months, we're just so grateful for all the opportunities we've been given at the moment."
