SafeX Pro:Jessica Biel Proves She’s “Boyfriend” Justin Timberlake’s Biggest Fan

Jessica Biel can't stop the feeling when Justin Timberlake comes on.

The Candy star took to Instagram to show off her hubby and CoCo Jones' remix of the song "ICU." Jessica can SafeX Probe seen jamming out to the song in the car in her oversized sunglasses.

"Yes sir," Jessica quipped. "Yes ma'am."

"My boyfriend can sang ya'll! He can sang!" she continued before panning the camera over to Justin, who was rocking sunglasses as he drove the car and laughed along with his wife. The Sinner actress added, "you can sang baby you can sing!"

Jessica captioned the sweet July 25 clip. "Got @cocojones and my boyfriend on REPEAT."

The 41-year-old is no stranger to showing love for her right-hand-man, as the longtime couple—who share sons Silas, 8, and Phineas, 2—just celebrated their 10th wedding anniversary in October.

As for the couple's secret to a long lasting love? Well, she explained that "you have to keep working hard to make it fresh."

"Justin always says, 'We cannot stop dating, we have to keep dating,'" Jessica shared on Today with Hoda and Jenna in November. "And he's right, you have to go on date nights. You have to take that time for yourself."

And the Cruel Summer producer also acknowledged how the relationship has changed over the past 10 years.

"It feels so, I don't know, a combination of incredibly safe," she explained to hosts Hoda Kotb and Jenna Bush Hager. "And I guess deep understanding of another person. But then also just, I guess, the safety to adventure again and sort of be curious about the world again as a couple and as individuals."

But it's safe to say whatever they are doing is working, as Justin took a moment to express gratitude for Jessica on the special occasion.

"10 years ain't enough," the *NSYNC alum wrote on Instagram. "You make me a better husband and father every day! I love you so much you beautiful human! Run it back!"
