The Sinner actress decided to get in some sizzle when she saw her leading man's latest Instagram post.
Timberlake shared a snap of himself concentrating in front of his laptop and wrote, “Doing work… on my book.”
Biel, clearly impressed, replied, “My wordsmith at work. Always in awe of your big… brain.”
And fans were living for it.
“Y’all are so much fun in how you play with each other,” one commenter wrote. Another added: “That’s the kind of positivity we needed this monday.”
It's a big time in the Timberlake-Biel household, with the singer is set to release his memoir Hindsight: & All the Things I Can’t See in Front of Me — which starts with the performer’s childhood in Memphis, Tennessee.
“Working on this book was an amazing process for me,” Timberlake, who co-wrote the book with Sandra Bark, said in a press release.
“My story has been filled with so many amazing people that have helped me become the artist I am today. Reflecting on those moments, spotlighting some of the important people and places that have informed my music, and getting the opportunity to share my story is something I am very grateful for.”
No doubt there will be a few pages dedicated to his wife.
The couple recently stepped out for the 2018 Emmy Awards - and Timberlake couldn't have been prouder of his partner, who was nominated.
“I’m more geeked out than she is,” Timberlake said. “I found out about the nomination before she did — she was in Europe, actually, when the nominations came out — but, yeah, I was there to watch her option this and develop it from scratch … I saw how much she put into it. And so, I’m just so proud to be here and see this happen for her.”
