Ronan Keating thanked his fans for their support during a recent gig amid allegations of his infidelity to wife Yvonne.
The Boyzone singer told the audience: "It has been a really scary time. Thanks so much for all the support from you over the past few weeks. You were the ones who kept me going".
The singer made the announcement during a solo set at the Henley Festival, a small gig in Oxon.
The singer and his wife Yvonne, who have been married for 12 years, announced their split on May 20 saying that the separation is amicable and that "they will continue to work together in order to provide the best for their children".
Since then there have been reports that the Boyzone singer had a seven-month affair with backing-dancer, Francine Cornell.
Ronan is currently filming Australia's Got Talent, where he is a judge on the show.
