#RelationshipGoals!

At the U.S. Open match in New York City between Roger Federer and Feliciano Lopez, Justin Timberlake and Jessica Biel cheered on the players and shared a sweet kiss.

The couple enjoyed a date night without their 2-year-old son, Silas, and were cracking each other up in the stands.

The pair are adorably in love, but know that making a marriage last takes some effort.

In August, Biel told Marie Claire what makes their marriage work. “We have similar values; we believe in loyalty, honesty,” she said. “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!”
