Ewan McGregor has revealed that he didn't know what kind of woman he was looking for when he met his wife Eve Mavrakis.

The actor, who met French production designer Mavrakis on the set of the TV show Kavanagh QC 16 years ago, told the Daily Mail that he doesn't know what keeps their marriage going strong.

He told the Daily Mail: "I don't know what keeps us together. I hit 40 this year and I've got friends of the same age who haven't found a partner yet.

"I didn't have a checklist for my ideal woman. I was very young when we met, and I just fell in love with her and knew I wanted to be with her, and I still want to be with her."

McGregor added that he and Mavrakis are rearing their children to have traditional values like politeness and manners.

He said: "We go back to visit my mum and dad in Crieff every summer and the kids love it. My knowledge of parenting comes directly from the way I was raised by my parents - I think that politeness and manners are very important."
