Justin Timberlake reveals the moment he fell in love with Jessica Biel

We're all for a celebrity love story - and it seems we're more in need of them than ever - given that 2018 has been the year of A-lister heartbreak.

Last year, golden couple Anna Faris and Chris Pratt called time on their 10-year relationship. And it seems to have provoked a veritable domino effect, with Jennifer Aniston and Justin Theroux separating earlier this year, and then Channing Tatum and Jenna Dewan divorced after nine years of marriage.

Justin Timberlake and Jessica Biel, on the other hand, are a couple who only seem to be going from strength to strength. In Justin's new book, Hindsight: & All the Things I Can't See in Front of Me, the singer speaks about how he and his wife of six years initially fell for each other.

Per People, Justin and Jessica first bonded over their shared sense of humour, but it took a while for them to get things going after that.

"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," the 37-year-old wrote. "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 humour, too."

Despite their obvious connection, Justin didn't ask for Jessica's number, and before he saw her again at a show during his FutureSex/LoveSounds tour, he had to summon some serious courage. "I had to psych myself up," he stated. "I had to remind myself that I was me—giving myself a pep talk, shadow boxing with myself, rubbing my own shoulders."

He finally got Jessica's number that night, and they started dating, although they weren't monogamous at first. "We were both still seeing other people, keeping ourselves safe from getting hurt, from really putting ourselves out there," Justin explained. "It took a bit for both of us to admit to ourselves that we were really, really into each other."

The pair decided to be exclusive after spending a month together following Justin's return from a trip overseas.

"We’ve had a lot of unforgettable times," the Mirrors singer continued. "She’s become a huge influence on my life, and I have such an admiration for her, especially seeing her as a mother now. 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."

"It’s as simple as having someone there to open that pickle jar when you can’t get it open and as complicated as deciding to be in each other’s lives forever," Jessica told People in a 2012 interview about deciding to tie the knot with Justin. "That kind of commitment is very special, and we were ready to jump."

Justin and Jessica married in 2012, and they welcomed their first child, Silas, in 2015.
