Justin Timberlake put down the “Suit & Tie” for something a little more Jessica Biel-centric at his latest gig — and she returned the favor!

The 10-time Grammy winner, 44, surprised fans on Saturday, May 24, when he took the stage at the BottleRock Napa Valley festival in a checkered jacket and white button-up, before removing both to reveal a distressed white shirt featuring his wife’s face printed on the front.

Timberlake’s T-shirt featured an early ’00s photo of the actress wearing a white tank top and jeans. He paired the cut-up shirt with white pants, a chain necklace and some shades.

But he wasn’t the only one wearing his heart on his short sleeves!

Biel, 43, was apparently in the crowd cheering on her husband during his set, as seen in snaps he later shared on Instagram. She showed her support by wearing her own piece of throwback JT merch for the occasion.

In an image shared by Timberlake, the couple smiled together backstage — with the singer in his custom Biel T-shirt and his wife in a 2003 Justified World Tour T-shirt.

“We out here fan girling 😍😍,” Timberlake captioned the snap.

On her own Instagram Stories, Biel shared a cheeky response to Timberlake’s shirt: “He really outdid the doer,” she wrote.

Timberlake’s latest carousel post also included a video of the pair admiring their outfits, as he walked out of his dressing room to ask Biel, “Let me see your T-shirt, babe.”

“Oh, is that what you’re doing?” Timberlake asked, as the camera panned to Biel wearing her black Justified shirt with matching black jeans.

“That’s what I’m doing,” she responded, before Timberlake revealed his own shirt to her with a “bam.”

The pop star then confirmed that he and his team “made” the Biel shirt just for the show, as he asked one of their two children “who’s this” while showing off the top. Biel and Timberlake share sons Silas, 10, and Phineas, 4.

As for the performance itself, Timberlake’s latest stint at the Napa Valley festival marked his first gig since April, as he performed hits including “SexyBack” and “Selfish.”

Speaking with InStyle for her cover story earlier this month, Biel revealed that she and Timberlake have plenty of history when it comes to T-shirts. As she shared, the actress stole one of Timberlake’s T-shirts almost 20 years ago and never gave it back, mostly because the smell of him on it gave her comfort.

“I would always want to have something of his to travel with. You know, something that just makes you feel like home, makes you feel connected to that person. It smelled like him, now it smells like me, which is a bummer,” Biel explained.

She confessed that the shirt — which belonged to Timberlake in childhood — is “on its last leg,” but said the torn-up tee has become a symbol of their relationship. The duo have been married for nearly 13 years.

“I think having a partnership that understands this industry and adjacent industries has been deeply important and profound for my life and for our partnership because he just understands when I’m working crazy long hours and I understand that for him too,” Biel also told InStyle, offering insight into their marriage.

“I get it when he works all night long. That’s kinda normal and I know that,” she added.
