The famously private pair have offered a rare insight into the relationship.
“I love them together!!! I hope they stay happily married for at least another 10!!! God bless them!!!” wrote one fan.
Now, Timberlake and Biel began dating in 2007 before tying the knot in 2012.
But in recent years they have been embroiled in some serious relationship drama.
According to Us Weekly, the relationship began when Timberlake then called Biel on the phone to ask her out, and of course, she said yes.
Things got serious!
And just a few months into dating, they went public, with the Daily Mail sharing photos of them kissing in the UK.
They were love’s young dream…
But, an incident catapulted them into the spotlight… and not for the best of reasons.
A cheating scandal suggested this couple might not be the relationship goals everyone thought they were.
After the singer had made such a big deal out of Britney Spears cheating on him back in the day, the public instantly began calling Timberlake out as a hypocrite.
When they broke up in 2002, Spears tried to minimize public speculation by saying they’d decided to mutually split.
Timberlake then made assertions that Spears had been getting close to her choreographer.
He’s basically the ex from hell.
He then went on to write ‘Cry Me A River’ as a diss track and later released ‘What Goes Around… Comes Around’ years later when Spears announced her divorce from Kevin Federline.
And those who remember his past with Spears are pretty sure he’s willing to throw other women under the bus to save his reputation.
On the set of Palmer, Timberlake, and actress Alisha Wainwright were seen spending some “quality time” with each other, which then led to spending more time outside of working hours.
Timberlake really messed up that time…
It was so bad that he was even forced to address the whole thing in a lengthy Instagram post.
He told fans he was going to be focusing more on his family and his “amazing wife.”
And soon after, news emerged that Biel and Timberlake had welcomed their second child.
Their eldest son is called Silas and is currently 7-years-old, but he became an older brother to the newest member of their family.
According to the Daily Mail, Biel had been pregnant since March 2019 (yes, while Timberlake was having an alleged fling with Wainwright!) and has now given birth to a beautiful baby boy called Phineas.
Timberlake’s friend and collaborator, Brian McKnight, casually confirmed that his friend had welcomed a new baby during a recent interview.
“Having kids and having his family, I think [Justin] took some time to focus on those things because those things are very important,” he revealed.
“I think if he’s going to do music, he’s going to make sure that that’s secure, and then he’ll bring us into his music.
“And being inspired! He just had a new baby. I think that’s going to be really inspiring for him and he’ll have some new music based on that, I’m sure,” McKnight said.
And now, the pair have revealed decided to renew their vows.
This romantic gesture is to make the occasion of the couple’s tenth anniversary!
They even traveled back to the location of their wedding in Italy.
“From our vow renewal this summer,” wrote Biel in an Insta story. “In Italy where it all went down.”
“10 years ain’t enough!” Timberlake wrote.
“You make me a better husband and father every day! I love you so much you beautiful human! Run it back!”
“Being married to you is the adventure of a lifetime! Run it back, baby. RUN IT BACK. I love you.” Biel responded.
Congratulations to the pair!
