*NSYNC member Joey Fatone made a surprise appearance at the My2K Tour event last weekend and performed with 98 Degrees. As a treat to fans, the boyband and Fatone performed a cover of *NSYNC's "Bye Bye Bye" hit complete with the song's original dance choreography.

The unforgettable collaboration happened during the My2K Tour concert in West Palm Beach, Florida, which featured appearances by O-Town, Ryan Cabrera and Dream, according to Pop Sugar.

During their set, a member of 98 Degrees introduced Fatone to the crowd. The NSYNC member then appeared on stage wearing the same clothes as Nick Lachey, Jeff Timmons, Justin Jeffre and Drew Lachey.

Dressed in their matching camouflage pants and tactical vests, 98 Degrees and 39-year-old Fatone then performed "Bye Bye Bye," the 2000 hit song from *NSYNC's second studio album, No Strings Attached.

The crowd went wild as Fatone kicked off the song. The members of 98 Degrees then joined in at the chorus and danced the choreography to the song, which was the same as *NSYNC used in the video for "Bye Bye Bye," Billboard reported.

The collaboration between Fatone and 98 Degrees is certainly a special treat especially for fans of groups from the boyband era. Hopefully, Nick Lachey's group will feature other crossovers in their upcoming performances for the My2K Tour.

As for the nationwide event, the next stop for the tour is Greenville, South Carolina. Then, for the rest of the week, 98 Degrees and the other featured artists and groups will head out to Alabama, Massachusetts, Georgia and Virginia.

Aside from performing their hit songs, such as "Invisible Man," "I Do (Cherish You)" and "The Hardest Thing," doing cover medleys of songs from other artists and groups is also part of 98 Degrees' set list for the tour. Other than "Bye Bye Bye," the other songs included in the medley are "Summer Girls" from LFO, "Fly" by Sugar Ray, "I Want it That Way" by the Backstreet Boys, "All the Small Things" from Blink-182 and "Baby One More Time" by Britney Spears.
