Here's how Justin Timberlake and Jessica Biel fell in love

In his first book, singer Justin Timberlake has opened up about how he fell in love with wife Jessica Biel.

The singer-songwriter, while sharing his love story in the book titled "Hindsight: And All the Things I Can't See in Front of Me", wrote, "When I met Jess, it was undeniable how beautiful she is."

"I made some sort of sarcastic comment, really dry. Nobody got it except her. She laughed, and I noticed, all of a sudden, and in the way where you wonder if a person's like you, if they have a very dry, dark sense of humor, too," he narrated.

According to People magazine, while Timberlake did sense a special connection with Biel, he did not ask for her number at once. "I'm kind of really interested in that girl. There was just something about that girl. Kind of interested in that girl. Goddamnit," he wrote.

Revealing how they were initially taking things slow, the 'Can't Stop The Feeling!' singer wrote, "We were both still seeing other people, keeping ourselves safe from getting hurt, from really putting ourselves out there. It took a bit for both of us to admit to ourselves that we were really, really into each other."

It was after he came back from an overseas tour that Timberlake and Biel decided to spend a month together. "We've had a lot of unforgettable times. She's become a huge influence on my life, and I have such an admiration for her, especially seeing her as a mother now," explained the hit maker.

The 'Say Something' singer went on to say that his wife was one of the most patient people he ever met, adding, "She's a very good writer. She's a poet. She's a tremendous actor. She's funny. Very funny. And she's one of the most patient people I've ever met. She changed me. She changed my life."

Timberlake and Biel tied the knot in Puglia, Italy on October 19, 2012, and have a three-year-old son, Silas Timberlake.
