Washington, March 1 : Rachel McAdams has revealed that she likes to stay friends with her ex-boyfriends because she got to learn something from all of them.

The `Vow' actress has been in a relationship with Michael Sheen for 18 months.

She feels "tenderness" towards her former partners, who include Ryan Gosling and Josh Lucas, because of the things they have taught her.

"Am I still friends with my old boyfriends? Yes, absolutely. There's no one who's ever been significantly in my life for whom I don't have a sort of tenderness because they helped to shape who I am," Contactmusic quoted her as saying.

The 33-year-old beauty thinks it is particularly important to be able to laugh at problems thus she values sense of humour the most in a partner.

"The ability to laugh together and not take anything too seriously is essential. It''s a way to connect that forgives a lot of other things and it allows you to move on much more quickly if there's a problem," she added to Britain's HELLO magazine. (ANI)
