John Travolta admits he has to work hard at his marriage. The "Hairspray" star - who has two children, Jett, 14, and seven-year-old Ella with wife Kelly Preston - believes marriage is a life-long commitment and isn't always easy.
John is quoted by Britain's Daily Mail newspaper as saying: "We've been married for almost 16 years and we have to work at it. Most people forget that you have to create relationships. The allure of the first years settles down and at that moment, you better start creating it, otherwise you're going to lose out."
