New Delhi, June 8 : Kiefer Sutherland says that he's just concentrating on his hit US TV show ''24'' and doesn''t have time for romance.

The actor, who has been through two divorces and was engaged to Julia Roberts, insists that his first priority is his work, reports the China Daily.

"My relationship is with ''24''. I owe her. It has taught me more about acting than any other job. In eight years I have made a group of friends who are like a family to me," he said.

"I have other relationships, but I don''t have as much time for that as I would like," he added.

Kiefer also admits that his failed relationships have put him off committing to a woman again.

"I have seen some of the greatest couples I know torn apart by marriage. People quit each other. They take everything for granted," he said.

"I was married for nine years and wasn''t successful at it. I am still best friends with my ex-wife but I try not to repeat the same mistake twice," he added. (ANI)
