Justin and Jessica were first linked in January 2007, when they reportedly chatted at a Golden Globes afterparty. Soon after, they went snowboarding together at the Sundance Film Festival, and by May, Justin was "in love" with her.
The couple split in March 2011, but just a few months later, Justin called Jessica "the single-handedly most significant person" in his life in an interview with Vanity Fair.
Justin and Jessica were spotted together in Toronto in August 2011, and news of their engagement broke in January 2012. The couple tied the knot in Southern Italy that October.
Although the pair is pretty private about their relationship, he did gush to Ellen DeGeneres about his wife when he appeared on her show in April 2013, saying, "Every once in a while I catch a glimpse of her when she doesn't see me looking and I have this moment where I'm like, 'If you never make a good decision, if you only make bad decisions for the rest of your life, you made one really good decision." He added, "It's nice to marry your best friend. It suits me."
The couple's son, Silas Randall Timberlake, shares JT's middle name, which is also his father's name.
