Justin Timberlake and ‘N Sync are once again back in harmony.

On March 13, the group surprised fans when they showed up at Timberlake's concert in Los Angeles to perform their new song, "Paradise," which will be featured on the singer's upcoming album, "Everything I Thought It Was."

However, they also performed a few fan favorites too, such as, “It’s Gonna Be Me” and “Bye Bye Bye.”

In fan videos that were shared on Timberlake's Instagram Stories, you can hear the crowd screaming once Timberlake's former band members — JC Chasez, Lance Bass, Chris Kirkpatrick and Joey Fatone — joined him on stage.

Chrissy Teigen, who was in the audience with her husband, John Legend, looked shocked to see their reunion.

"Oh my f--king god," she wrote above a video she shared of the group on stage.

"One of the best days of my life. we're not crying.. you're crying," a fan said on IG on their Instagram Story.

One fan shared an IG story of the performance, which Timberlake reposted on his own account, writing, "I can't believe @nsync came out I am not ok."

After their iconic performance, Timberlake shared a photo of five stools on stage, and captioned it, "That was fun. Let’s do it again soon. 😁."

According to Variety, the five band members have not performed live together since the 2013 VMAs.

On March 4, fans learned that Timberlake was teaming up with ‘N Sync on a single when he and Spotify both shared a photo of his track list for "Everything I Thought It Was" on Instagram.

"We’ve got the track list for Justin Timberlake’s upcoming album Everything I Thought It Was Countdown to March 15 on Spotify," the post read.

The image confirmed that Track 17 titled "Paradise" featured the beloved '90s boy band.

On Feb. 28, Timberlake first fueled speculation that he and ‘N Sync could reunite for "Everything I Thought It Was" when he shared a video of himself responding to a fan’s TikTok comment.

The comment referenced Timberlake's new song "Paradise."

“Blink twice if *NSYNC is on a song called Paradise," the comment read.

Looking into his camera, Timberlake pulled down the sunglasses he was wearing and then blinked twice.

"I’m literally freaking out !!!!!!" the official TikTok account of iHeartRadio commented.

Another commenter said, "Omg 😳 I’m going to get all my posters back out and put them on my wall…husband can deal with it 🏃‍♀️."

"OMG ITS HAPPENING!!! The man himself is confirming!!! Thank you for giving us more @*NSYNC 💗💗💗💗💗," a third added.

Timberlake's new album, "Everything I Thought It Was," is set to be released on March 15, according to RCA Records. The singer dropped the first single, titled "Selfish," in January.

Timberlake, who is married to Jessica Biel, previously reunited with his ‘N Sync band members to record the track “Better Place” for the 2023 animated movie "Trolls Band Together," in which Timberlake voices a leading role.

"That was fun," he told Kelly Clarkson while on her talk show in January about what it was like to reunite with ‘N Sync. "It's kind of crazy like, there's so much that just picks up right where it left off as far as the chemistry."

Timberlake also teased some new music from the group during his appearance on Clarkson's show.

“We’ve been in the studio, so there may be a little something in the future, too,” he said as Clarkson's studio audience cheered.

"That's exciting," she replied.
