Singer Justin Timberlake took a breather in his busy schedule to surprise both his fans and wife, Jessica Biel, by posting a video in one of his social media accounts.  

In his Instagram post from Oct. 19, the "Not a Bad Thing" singer expressed his love for his wife, "The Sinner" actress Jessica Biel, as the couple celebrated their 5th wedding anniversary. Timberlake also made a low-key announcement that he had been brewing something in the studio.

The Grammy Award winner took to the media-sharing platform to share a video of his rendition of the song "A Song For You" originally by Leon Russell, which Timberlake revealed was the song to his and Biel's first dance. He took a break from his work, discreetly confirming that something was in the works.

The former N-sync member went on to say that he was the "luckiest man" when he married Biel five years ago. "You have taught me so much about what a true love means. I can't put into words what these last five years have meant to me," added Timberlake. His wife also reposted the video in her Instagram account with the caption, "My tender heart is yours, now until forever."

The "Total Recall" actress also shared a cute video of her and her beau on the back seat of a car. Biel, seen using a cat floral filter, was playing around when she panned the camera to Timberlake, who was at first didn't get with Biel's actions. But he quickly went with his wife's antics. The "Accidental Love" star divulged in the caption that her hubby "gets extra" for her even when he has reservations. 

Timberlake and Biel got married in a southern Italian resort, Borgo Egnazia. They were together for five years before deciding to exchange vows. The couple is blessed with a 2-year-old boy, Silas Randall.
