It's tearing up our hearts, but what can we say? We want NSYNC back...

Accepting Stephen Colbert and Nick Kroll's #PuberMe Challenge, NSYNC member Lance Bass took to Instagram and kept it totally '90s earlier today, sharing a delightfully awkward photo of his fellow boybanders Justin Timberlake, JC Chasez, Chris Kirkpatrick and Joey Fatone 22 years to the day that the group all met in Orlando, Florida.

Along with the epic throwback photo, the 38-year-old wrote, "22 years ago today I met these jackasses. My life would never be the same. Happy #NsyncDay #PuberMe #PuertoRicoRelief."

On a recent episode of The Late Show, Kroll dared Colbert to share an awkward photo of himself with the hashtags #PuberMe" and #PuertoRicorelief to raise awareness and money for the people of Puerto Rico after Hurricane Maria's destruction. Many celebrities, including Reese Witherspoon, Conan O'Brien and Lin-Manuel Miranda, heeded the call.

It's been a busy week for the singer. Bass' new MTV show, 90's House, just premiered. The competition show places 12 millennial housemates in a '90s-inspired house and is hosted by Bass and Christina Milian.

Oh for those of you who are interested (which we know you are), Bass did confirm to InStyle that the boys were getting the band back together for a reunion very soon.

The singer said, "We'll be getting back together in a few months when we get our star on the Hollywood Walk of Fame. We're just planning that celebration right now. It'll be really fun!"

So if you are feeling nostalgic (which, once again, we know you are), take a look at Bass and the rest of the brave souls who accepted the #PuberMe Challenge...

Many celebrities also heeded the call.

"Here you go @nickkroll... giant glasses, awkward hands, feeling 14! All for a good cause. God Bless Puerto Rico. #PuberMe #PuertoRicoRelief," the actress wrote on Instagram.
