98 Degrees (seen here performing in 1999) announced in May that they will be heading out on a holiday music tour for the 2018 season. Made up of brothers Nick and Drew Lachey, Justin Jeffre and Jeff Timmons. The group released three albums, in addition to one Christmas album, between 1997 and 2000. Their album, "2.0," arrived in 2013 and they released a Christmas album, "Let It Snow," in 2017. Scott Gries/ImageDirect/Getty Images
In 1996, the Backstreet Boys released their debut album, "Backstreet's Back." "Millennium," "Black & Blue," "Never Gone," "Unbreakable" and "This Is Us" followed. After parting with the group years ago, Kevin Richardson (second from left) rejoined A.J. McLean, Howie Dorough, Nick Carter and Brian Littrell. In March 2017, they kicked off a limited Vegas residency and they released a new single in May. Kevin Mazur/WireImage/getty images
*NSYNC members Lance Bass, Chris Kirkpatrick, Justin Timberlake, JC Chasez and Joey Fatone struck gold in the United States with "I Want You Back" in 1998. Before they broke up in 2002, the group established a mega fan base with songs like "No Strings Attached" and "Bye, Bye, Bye." Although they're not together anymore, *NSYNC is as popular as ever; you should've heard the shrieking their reunion at the 2013 MTV Video Music Awards caused.

As One Direction, Liam Payne, Louis Tomlinson, Zayn Malik, Niall Horan and Harry Styles are heartthrobs -- not unlike the Rolling Stones were once upon a time, Mick Jagger told CNN. Malik announced in 2015 that he'd be leaving the group and the remaining members went on hiatus the following year to fans' dismay. Eamonn McCormac/Getty Images
Luke Hemmings, Michael Clifford, Calum Hood and Ashton Irwin met in the Western Sydney suburbs and played their first gig as 5 Seconds of Summer at a Sydney hotel in 2011. They grew their fan base by posting videos on YouTube, and soon enough, they were opening for One Direction. Their self-titled debut album was released in 2014 and debuted at No. 1 on the U.S. Billboard chart. Chiaki Nozu/WireImage/Getty Images
Though they never made it big in the U.S., boy band Westlife was a huge hit in their native Ireland. They'd sold more than 50 million copies of their albums worldwide by the time they disbanded in 2012. Irish Government/Getty Images

Danny Wood, Donnie Wahlberg, Jordan Knight, Joey McIntyre and Jonathan Knight of New Kids on the Block perform live in 2008. The group, which rose to superstardom in the late '80s and early '90s, reunited for 2008's "The Block" and 2011's "NKOTBSB" with the Backstreet Boys. The Kids released their box set "10" in 2013.

Ralph Tresvant, Michael Bivins, Ronnie DeVoe, Ricky Bell, Bobby Brown and Johnny Gill of New Edition perform an homage to Michael Jackson during the 2009 BET Awards. The R&B group's albums include 1983's "Candy Girl" and 1988's "Heart Break," among others. Kevin Winter/Getty Images

The Wanted released their self-titled debut album in 2010, and by 2012 their song "Glad You Came" was inescapable. Jay McGuiness, Nathan Sykes, Max George, Siva Kaneswaran and Tom Parker, here after receiving a 2013 People's Choice award, are repped by Justin Bieber's manager Scooter Braun, so they know a thing or two about heartthrobbing. The group has appeared on TV in the E! reality show "The Wanted Life," and their album "Word of Mouth" was released in September 2013. Christopher Polk/Getty Images for PCA
Menudo performs in 2008. Originally formed in the '70s, they helped launch Ricky Martin's career. The boy band has had many members over the years. Bryan Bedder/Getty Images
The made-for-TV boy band 2gether debuted on MTV in 2000. Shown here at the 2000 MTV Movie Awards, the guys attracted attention with songs like "U + Me = Us (Calculus)" and "Say It (Don't Spray It)." "2ge+her: The Series" followed the original TV movie, but ended in 2001 when member Michael Cuccione died of cancer. In November 2011, Alex Solowitz, Evan Farmer, Noah Bastian and Kevin Farley said they were looking to reunite the band. Frank Micelotta/Getty Images
The Boys released three albums between 1988 and 1992. "Dial My Heart" was the debut single from brothers Khiry, Hakim, Tajh and Bilal Abdulsamad.
