The guys of *NSYNC have come a long way since their days of frosted tips and all-denim outfits [2], but that doesn't mean they've stopped being friends. For the first time since their epic performance at the 2013 VMAs [3], the gang got back together on Monday night in honor of JC Chasez's 40th birthday. Justin Timberlake posted a photo of the former boy band's reunion to Instagram [4], which showed him, JC, Chris Kirkpatrick, Joey Fatone, and Lance Bass getting close for the camera with the caption, "JC's 40th. . .And, if you don't know now you know. . ." Did they break out some vintage dance moves [5]? Talk about their adorable kids [6]? Wonder where Chris's dreads have gone? All we know for sure is that they must have joked around about how old they are now, since Chris tweeted [7] "Happy birthday @JCChasez ! Welcome to the old man club!" So cute! Take a look at the photo above, and then see what *NSYNC's biggest fangirls are up to now [8].
