The guys of *NSYNC have come a long way since their days of frosted tips and all-denim outfits, but that doesn't mean they've stopped being friends. For the first time since their epic performance at the 2013 VMAs, the gang got back together on Monday night in honour of JC Chasez's 40th birthday. Justin Timberlake posted a photo of the former boy band's reunion to Instagram, 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? Talk about their adorable kids? 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 "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.
