She was left devastated when reports revealed that her husband of 12 years, Ronan Keating, had been unfaithful with a Boyzone backing singer.
But it seems Yvonne has managed to forgive the star and the couple have well and truly ended their self-imposed separation in an attempt to make a fresh start.
"'Ronan is all about his family now. Nothing comes before them. Both he and Yvonne have discovered a new-found love for one another and are almost like love-struck teens again," says a source.
"They're chatting about the prospect of a new baby and are giddy with excitement. The future's definitely looking bright for them once more," he added.
