*NSYNC performs ‘Bye Bye Bye’ at Justin Timberlake’s LA concert

Hello hello hello.

*NSYNC fans went wild Wednesday as the popular ’90s boy band reunited for a surprise performance at Justin Timberlake‘s “one night only” show at the Wiltern in LA.

According to an Instagram Story posted by Timberlake, the venue opened the stage’s curtains to reveal JC Chasez, Lance Bass, Chris Kirkpatrick and Joey Fatone.

The group went on to sing their two greatest hits: “Bye Bye Bye” and “It’s Gonna Be Me.”

The surprises didn’t end there.

In a TikTok clip, the former heartthrobs gave attendees a sneak peek at their brand-new song “Paradise.”

“There is a song,” Chasez, 47, told the audience.

“By *NSYNC,” Timberlake chimed in, as Kirkpatrick, 52, quipped: ” A brand new song.”

“Which we practiced,” Chasez cracked.

The “Cry Me a River” crooner then asked the crowd if they wanted to hear a snippet of the track.

“You gotta buy the album, goodnight everybody,” Fatone, 47, joked, referring to Timberlake’s upcoming album “Everything I Thought It Was.”

After completing the song, the four members thanked the “SexyBack” singer for having them.

“Thank you, guys,” Fatone said.

As Timberlake hugged each of them, he remarked: “I love you guys so much.”

Following the show, the “Mirrors” singer posted a photo of five empty stools.

“That was fun. Let’s do it again soon.

,” Bass, 44, commented on the photo.

Speculation that the band reunited for a new song began last month.

The “Drown” singer showed off his new deluxe vinyl edition of the record Sunday on TikTok at the time.

“Blink twice if *NSYNC is on a song called ‘Paradise,’” one fan begged Timberlake.

The singer responded by pulling down his sunglasses and blinking twice in a video.

*NSYNC previously performed in 2013, when the “Suit &Tie” singer was presented the Video Vanguard Award during the MTV Video Music Awards.

Last year, they made headlines when they briefly reunited at the VMAs to present the award for Best Pop Video to Taylor Swift.

Shortly after the appearance, the group revealed that they had collaborated on a song for the “Trolls” film — also starring Timberlake — called “Better Place.”

The track marked the first time the group collaborated on new music since 2002, when a production company called The Neptunes released a remix of their 2001 song “Girlfriend.”
