Justin Timberlake wishes 'love of my life' Jessica Biel a happy birthday: 'I adore you'

Justin Timberlake is feeling sentimental — and funky — on wife Jessica Biel's birthday. "The Other Side" singer shared a tribute post to Biel, who turned 38 Tuesday, calling her "the love of my life" along with four personal photos.

"A new adventure every day and a treasure to me. I can’t wait to share many more of these with you," he wrote. "Thanks for putting up with me when I smell funky after a round of golf or, when I smell funky in general. You are the mostest of the mostest, my love! I adore you."

Biel appreciated the shoutout. She commented on his post, "As you always say, you can’t be funky if you don’t smell funky."

The actress and producer started her day with breakfast from her "boys," Timberlake and their 4-year-old son, Silas.

Birthday festivities really kicked off Monday as Biel’s husband of seven years threw her a pajama party.

"I made Justin PROMISE not to sing Happy Birthday to me, so he improvised," she shared on Instagram. "Thank you, you wonderful human, for really listening to me, and for throwing my kinda party."

Timberlake — who has made a habit out of writing very loving comments on Biel's posts since his co-star scandal — chimed in. He added, "I LOVE YOU!!! Happy Bday, you beautiful, loving, caring, wonderful [fox] of a mom and wife!!!

The 39-year-old singer and Biel have clearly recovered from Timberlake's "strong lapse in judgement" in November. The actor was photographed holding hands and engaging in PDA with his Palmer co-star, Alisha Wainwright, but maintained "nothing happened." In December, he publicly apologized to his wife and son.

"I drank way too much that night and regret my behavior," he declared on Instagram.

Biel hasn’t publicly addressed the incident. She was happy, though, to pause her birthday content on social media and encourage her followers to vote.
