Justin Timberlake reveals the secret behind his five year marriage to Jessica Biel

Sometimes with all the celebrity breakups and divorces, we hear about daily it can feel like no celebrity marriages last. 

Justin Timberlake and his wife Jessica Biel are celebrating five years together and Justin has revealed the secrets behind their strong marriage.

The singer appeared on the show The Project and said that the key to a successful relationship is making time for each other.

“That's always my rule, even when you get married you have to keep dating. It's just the difference comes when you have kids you have to actually schedule the date. So when you say you're going out at 6.30pm, you need to go out at 6.30pm.”

Earlier in the year, Biel spoke to Marie Claire about why she thinks they work so well together as a couple.

“We have similar values; we believe in loyalty, honesty. We like to have fun. We like a lot of the same things. Also, in the business, we're all very career-oriented, and you have to be a little selfish. I understand that about my peers — about being focused and driven — and if you can find that and someone who shares the same values as you, it's like: Score!”

And just when you think it couldn't get any cuter, it does.

Justin sang their song for the couple's anniversary this year and captioned the post: 

“You have taught me so much about what a true love means. I can't put into words what these last five years have meant to me."
