The couple is celebrating their fourth wedding anniversary on Oct. 19, and are clearly still going strong. Biel Instagrammed a cute photo of the two enjoying a low-key date night on Thursday, playing Scrabble and enjoying a glass of wine.
"I played 'sardine' and got the 50 bonus points! Guess who is no longer undefeated... #scrabblebrag," Biel captioned the adorable pic of Timberlake gazing at her with affection.
Earlier this month, the 35-year-old "Can't Stop the Feeling" singer got emotional when talking about his wife and son.
"I have this new appreciation for both of them, her and him," he told NBC News correspondent Willie Geist. "It's humiliating and humbling at the same time."
Biel, 34, also couldn't be more overjoyed with family life.
"I definitely have that unit feeling -- it's a good feeling, isn't it?" the actress said about having her own family during an interview with Today in May. "It's very insular, and it feels like, you against the world, and you can do anything. It's kind of like that aspirational feeling I guess."
