Waves of boy band nostalgia swept the internet earlier. Justin Timberlake posted a photo of the members of NSYNC celebrating JC Chasez's 40th birthday. This reunion has made many people wonder: what happened to the members of NSYNC? Are Lance Bass, JC Chasez, Joey Fatone, and Chris Kirkpatrick still in the music business, and what are their current projects like? The answers may surprise you.

Unsurprisingly, most former NSYNC members have continued to work as singers or songwriters in some capacity. Acting is also a common career path, and they have appeared in films ranging from My Big Fat Greek Wedding to Sharknado 3. But can you guess who has gone on to open a hot dog stand in Florida, and who has attempted to become a space tourist? One thing is certain: these men have enjoyed their fame and continued to work on some truly interesting projects.

Although the NSYNC members and their fanbase have grown up quite a bit, some things remain the same. These "man band" members are still tearing up hearts and screens the world over, and they are still cultural forces in their own right. And — not for nothing — they're all still pretty cute, right? I would hang that Instagram shot on my locker.

1. Lance Bass

After his stint in the original NSYNC lineup, Lance Bass's life took some amazing turns. At 23, he made a bid to become the youngest person in space, but producers failed to raise the $20 million fee for him to blast off from Kazakhstan, according to Billboard. Although he did not get to make it to the stars, his life took another important turn when he came out as gay to People Magazine in 2006. He has since become an important gay rights activist, and his marriage to Michael Turchin was the first gay wedding televised in America, as noted by The Daily Beast. And he's still a busy man: according to his Twitter page, Bass is set to host a gay reality dating show called Finding Prince Charming, and he has also been involved with The Meredith Vieira Show and My Kitchen Rules.

2. J.C. Chasez

Chasez pursued a solo career with his single "Blowin' Me Up (With Her Love)" and his 2004 album Schizophrenic. He has also worked as a songwriter for artists such as David Archuleta and the Backstreet Boys, according to Cliz Beats. In addition, he's had several television appearances, and he served as a judge on America's Best Dance Crew from 2008 to 2012.

3. Joey Fatone

Fatone has worked a ton since his time with NSYNC. He appeared as Angelo in 2002's My Big Fat Greek Wedding, and has had roles in Kim Possible, Hannah Montana, Jersey Shore Shark Attack, Army of the Damned, Dead 7, and Izzie's Way Home, according to IMBD. He was also on season 4 of Dancing With the Stars. In addition, Fatone has served as a host on My Family Recipe Rocks and Rewrapped. Oh, and he's launching a hot dog stand called Fat One's at a Florida mall, as noted in Time. He and his wife Kelly Baldwin have two kids, Brianna and Kloey, according to CBS News.

4. Chris Kirkpatrick

Kirkpatrick appeared in 2008's Gone Country 2 on CMT. According to IMDB, his other appearances on TV include Stripperella, The Fairly OddParents, Sharknado 3: Oh Hell No!, Dead 7, and Angie Tribeca. On the personal front, he married Karly Skladany in 2013, as noted in People.

5. Justin Timberlake

Does he even need a follow-up? His solo albums, Justified, Futuresex/Lovesounds, and The 20/20 Experience sold like crazy; in fact, 20/20 was the bestselling album of 2013, according to Billboard. His SNL appearances are legendary. And he's married to Jessica Biel.
