Ronan Keating seemed to be still haunted by a previous mistake as his estranged wife Yvonne Connolly kisses another man. Lucky for him, it was just a male fan.

Keating, who had a fling behind her back, was photographed as he was leaving the X Factor auditions where he is a judge.

Connolly was closely behind him and got some attention from a man in the crowd gathered outside.

She seemed happy to oblige her admirer as she gives him an innocent peck on the cheek.

Keating did not seem to be aware of what had happened behind him. He cut a solemn figure and walked determinedly after a day's work of judging in Melbourne.

The couple was also accompanied by their daughter Marie.

Last week, Keating and Connolly went to the Taronga Zoo in Sydney with their three children, Jack, Marie and Ali. Although the couple looked gloomy while they were walking around the zoo, the children seemed very happy with the trip.

Keating is now in Oz as a judge for the Australian version of The X Factor, along with Natalie Imbruglia and Guy Sebastian.

Connolly has accompanied him out there. Friends say this was a "good sign" and they were hoping that the two would eventually reconcile.

The couple got married in April 1998 on the Carribean island of Nevis, but announced they were going their separate ways in May of this year, calling their break-up "amicable".

Days after the announcement, reports surfaced that Keating had a fling with 26-year-old Francine Cornell, whom he met when she was hired as a backing dancer for a tour by Boyzone last year.
