Keating, 33, announced he had separated from wife Yvonne earlier this year amid claims he cheated on her with one of his band's backing dancers Francine Cornell.
However the Irish singer and his partner seem to have put their problems behind them as they are now back together and looking forward to a 'fresh start'.
He said: 'I'll be spending Christmas with my family and I can't wait. We're planning to move into our new home this week just in time. We've designed and built it ourselves.'
The couple recently attended a charity ball for the Marie Keating foundation and he said to guests: 'I just want to thank my wonderful wife for being here with me tonight. She means the world to me.'
