Lost actress Evangeline Lilly receives telephone calls from her parents every time she kisses a man on television, because they don't approve of public displays of affection.

While the Canadian actress, 26, is determined never to film gratuitous smooching scenes, she admits she has to field disapproving calls from her family on a regular basis.

Lilly says, "They're very conservative and they're very, very bothered by the kissing scenes I have to do.

"But being a Christian doesn't sit well in this industry. I don't mind kissing scenes if they're telling the story but I won't do them if they are gratuitous.

"Any time there anything even slightly risque on the show my family are on the phone saying, 'We didn't like that.'"
