Washington, July 8 : Penelope Cruz may never exchange wedding vows with beau Javier Bardem, for the actress has hinted that she doesn't believe in the concept of marriage.

The beauty also says that she has plans to start a family one day, but hints it could be at the expense of her acting career.

"I want to have babies one day but not right now. When I do it I want to do it really well. I want it to be my best project in life," Contactmusic quoted Cruz as saying.

"I don't know if I believe in marriage. I believe in family, love and children," she added. (ANI)
