Justin Timberlake did not shy away from expressing his love for his wife Jessica Biel on Wednesday to celebrate his wife’s 39th birthday.

“Happy Birthday to my favorite person in the world… the strongest, funniest, best, brightest and most beautiful mom/partner/BOSS there is,” the former NSYNC member wrote alongside with a carousel of photos of Biel. “I’m lucky to learn from you and laugh with you and celebrate you every day. But today we do do it with 🎂!!!!”

He added, “Here’s to more slow-mos in the wind, jumping into bushed to save out kid’s toys and timing out jump pics perfectly … I ❤️ U with all that I know.”

Timberlake’s post came a month after Biel posted a 40th birthday tribute to the singer.

“There’s no one I have more fun with, have more laughs with, feels more deeply for and have more history with,” she wrote at the time. “I honor you today, baby. And wish you the most creative and fulfilling year to date. Happy 40th, my love.”

The couple tied the knot in 2012 and parents to five-year old Silas and one-year-old Phineas.
