Justin Timberlake's birthday has kicked off on a high note.
The Justified singer is celebrating a milestone year, the big 40, so it's no surprise that his wife of nine years, Jessica Biel, made sure he's been feeling extra special. On Sunday, Jan. 31, the Total Recall actress shared a heartfelt tribute to the birthday boy on Instagram.
"There's no one I have more fun with, have more laughs with, feel more deeply for, and have more history with," she began her caption, alongside a collage of pictures that captured some of their sweetest moments together. "I honor you today, baby. And wish you the most creative and fulfilling year to date. Happy 40th, my love."
In recent months, the couple has toasted to many special occasions, including welcoming a second child, a baby boy named Phineas, who was born in 2020. The pair are also parents to 5-year-old son Silas.
When confirming he and Jessica expanded their family, Justin told Ellen DeGeneres on Jan. 18, "He's awesome and so cute, and nobody's sleeping... But we're thrilled. We're thrilled and couldn't be happier. Very grateful."
Adjusting to the arrival of their little one has been easy, as a source previously told E! News the couple has "spent the majority of their time in Montana over the last year. It's been a great break for them, with a lot of family time."
"Justin and Jessica have their hands full with the kids, but they are both super active and love to golf, play tennis, hike and snowboard," the source added. "Silas is old enough now that they can bring him along, and he loves it all, too. They have always loved it in Montana but never had a long enough break to live there full-time and really enjoy all that it has to offer... they are taking advantage of being out of the city and getting to have a completely different experience."
While the couple has kept a pretty low profile throughout their relationship, the "Better Days" singer recently said he'd like to be more open with his fans.
"I try to be conscious of making sure we can live a life where we're not weirdly private but we're conscious of making sure they can be kids for as long as possible," Justin told host Dax Shepard on the Armchair Expert podcast on Jan. 25. "And not have the weight of somebody else treating them differently because of something that their parents do."
