Justin Timberlake has surprising reaction when he spots *NSYNC members in concert crowd

Justin Timberlake was saying hi hi hi to his former *NSYNC bandmates.

The singer, 43, had some surprise guests in the audience while performing at the Thousand Palms, Calif., stop of his Forget Tomorrow World Tour.

JC Chasez, Lance Bass and Chris Kirkpatrick showed up to Timberlake’s concert as seen in Bass’s Tuesday TikTok video.

The footage shows the artist on stage as he spots the trio in the crowd.

“Why didn’t you guys text me?” Timberlake mouthed before laughing and turning back to the crowd.

The clip cuts to Bass dancing with the text reading: “On second thought, maybe we should have texted Justin before we showed up.”

Bass, 45, Chasez, 48, and Kirkpatrick, 53, continued to dance together in the audience as Timberlake performed on stage.

Missing from the action? Joey Fatone, 47, who was making his debut on Broadway in New York City at the time. The actor has taken over the role of Lance in “& Juliet” from actor Paulo Szot.

“In honor of Joey’s Broadway debut tonight,” Bass playfully wrote in the caption, “we had a date night without him.”

The pop star also shared a picture on Instagram that included Timberlake, to which Fatone commented, “You guys are the sweetest I appreciate it !!!!”

Fatone then shared his own Instagram post, Photoshopping himself into the reunion pic.

“Thank you, Chris for putting me in the photo,” Fatone captioned the cheeky shot. “It is perfect! I was definitely there in spirit!”

Last week, Fatone told the Post that the group needs to “have a conversation” about a future reunion.

“That’s really what it boils down to. And we’re gonna hopefully do that soon. We keep saying ‘soon,’ but it’s getting where it’s like either s—t or get off the pot,” he said. “Let’s be real.”

And with the 25th anniversary of *NSYNC’s blockbuster album “No Strings Attached” coming up in March, Fatone thinks that it’s time for “that moment of the five of us sitting down going, ‘OK, what does this look like? Do we want to do a tour? Is it just a tour? Is it an album? Is it an EP? Are we not going to do anything? Like, what exactly are we going to do?’”

Chasez would also be down for a reunion.

“You go where inspiration is, right?” he said during a November appearance on the “LadyGang” podcast. “I’m not one of those people that fakes it very well. Whenever I’ve tried to fake it, I’ve always felt s–tty about it, to be honest with you.”

But in July, TMZ reported that Timberlake was allegedly the big holdout on a reunion tour.

The outlet claimed that insiders revealed the “Reptile” star and his team did not respond to respective proposals for a possible *NSYNC stadium tour next summer, despite the other members showing interest.

But if a 2025 tour were to happen, it would perfectly coincide with the band’s 25th anniversary.
