Love-rat Ronan Keating tries to win back wife by dedicating love song

London: Irish singer Ronan has dedicated a love song to his wife Yvonne Connolly in an attempt to win her back.

The Boyzone star sang one of his romantic numbers `If tomorrow never comes`, begging his wife for forgiveness at a concert in Switzerland.

Keating looked ran out, pale and teary-eyed when he sang the song, reports a news daily.

"I just slept all day today. All I`ve been doing is resting. I would like to thank my mum and dad," the 33-year-old singer told fans at SkyDance festival about his agony after he had an affair with blonde dancer, 26-year-old Francine Cornell.

"Thanks to all of you. Until next time life truly is a roller coaster," he added.

Keating told his friends that giving a performance so soon after his break-up was announced was "the hardest thing he ever had to do."

"I know what I did was wrong. I feel terrible about what this has done to Yvonne but I`m not prepared to give up on my marriage," a source quoted Keating when he told his friends about his affair.

"I`ve cancelled everything for the next three weeks and I`m going to go back to Dublin to try and make this work," the source added.

It is reported that Connolly had discovered several naughty text messages from Francine on Keating`s secret mobile phone.
