Jessica Biel and Justin Timberlake are one of Hollywood’s power couples. But at the start of their relationship, they agreed to see other people to avoid “getting hurt.”

In a new book titled “Hindsight: And All the Things I Can’t See in Front of Me,” Timberlake said that they began dating around the time of the 2007 Golden Globes, but they weren’t exclusive.

“We were both still seeing other people, keeping ourselves safe from getting hurt, from really putting ourselves out there,” he wrote. “It took a bit for both of us to admit to ourselves that we were really, really that into each other.”

Timberlake and Biel first met at a Hollywood surprise party. They started talking later that evening, after Biel was the only person who laughed at a "dry" and "sarcastic comment" that he made.

The pair reunited during the first show of Timberlake's "Future Sex/Love Sounds" tour, which kicked off in San Diego, California on January 8, 2007. Once the "Mirrors" singer got Biel's number, they talked on the phone for two weeks as he continued his tour.

In his book, Timberlake explained that once he returned from performing around the world, the couple spent a month together.

"After that, I said, 'I really want to be exclusive.' And, somehow, she said, 'So do I,'" Timberlake said.

The pair continued stepping out together, but broke up in 2011. They remained friends following the split, and got back together shortly after. In December 2011, Timberlake proposed to Biel and they got married the following year.

Now, the couple has a son named Silas (born in 2015), who inspired Timberlake to write his chart-topping "Trolls" song "Can't Stop the Feeling." On his most recent album, "Man of the Woods," the 37-year-old also included Biel's voice in an interlude titled "Hers," because he considers her "a narrator, or a voice of consciousness."
