The group's loyal followers camped out overnight to get the best spot at the boy band's Hollywood Walk of Fame induction.

*NSYNC fans camped out overnight in Hollywood ahead of the boy band’s induction on the Walk of Fame on Monday.

A queue of fans began forming around 6.30 p.m. on Sunday and was winding around the block by the time Monday morning rolled around.

The mainly female crowd enjoyed singalongs and donned throwback merchandise including T-shirts from the group’s 2000 No Strings Attached tour.

The quintet, comprised of JC Chasez, Joey Fatone, Justin Timberlake, Chris Kirkpatrick and Lance Bass, will receive the Hollywood Walk of Fame’s 2,636th star, which will sit alongside the stars of fellow male vocal groups the Backstreet Boys, New Kids on the Block and Boyz II Men.

To celebrate the achievement, the group opened up the Dirty Pop-Up store, featuring fun photo opportunities and merchandise. ET caught up with Chasez at the store to find out what people can expect from the Walk of Fame ceremony.

“It’s not really about us -- we’re happy to be there, but at that point that star is mainly for the fans,” Chasez, 41, said. “The fans made this happen and that’s why we did something like this. They gave us the opportunity to share our music with people and it was important for us to do something for them.”

Chasez also revealed that, like many fans attending the ceremony, the group had already discussed what to wear!

“We agreed on dressy casual,” shared the musician, who has put out solo music, written and produced songs for acts including the Backstreet Boys and launched an all-female group, Girl Radical, since splitting with *NSYNC.  “So, we’re not necessarily going to match. [We’ve] spoken amongst ourselves and said, ‘You know what, let’s do dressy casual -- don’t show up looking like you threw on your bathrobe.'"

On the eve of the ceremony -- which will stream online at 11 a.m. PST -- fans who weren’t in line hit up the second of Timberlake’s two Man of the Woods concerts at The Forum in Los Angeles.

Before Timberlake hit the stage, crowds of concertgoers gathered outside the venue and sang along to the *NSYNC hit, “Bye Bye Bye,” then lined up for photos with a cardboard cut-out of the crooner.

Celebrities including Ellen DeGeneres -- who will speak at Monday’s ceremony -- AJ McLean and Nick Lachey enjoyed Timberlake dancing his way around an elaborate three-part stage while performing his hits including “What Goes Around Comes Around,” and “Can’t Stop the Feeling.”

The concert also featured a cozy set around a campfire, mesmerizing visual projections and woodsy stage décor like fake trees and grass.
