Something amazing happened in Las Vegas over the weekend. Former *NSYNC member Lance Bass joined The Backstreet Boys onstage, and the Backstreet Boys straight up serenaded their boy band brother in arms, according to Entertainment Weekly. And yes, there is video evidence of this momentous moment, so you can watch it as many times as your heart desires.

Bass and his husband, Michael Turchin, were attending the show when Bass went up on stage to hang out with the guys while they sang "Shape of Your Heart." While I cannot say they were 100 percent singing the anthem to Bass alone, the mutual lovefest between the guys was clear. There were hugs and high fives all around — surely melting the hearts of every '90s kid in the audience.

While you and your BFFs no doubt spent many hours debating which band was better — *NSYNC or The Backstreet Boys — both bands have made it clear there was no rivalry between them, just love. Seeing how adorable they are together these days serves as a reminder that both of the bands were always awesome and talented.

The Backstreet Boys even took to their official Twitter account to praise Bass, and thank him for coming to the show. Is anyone else crying? Because I am totally crying.

For his part, Turchin was clearly just as excited as the rest of the audience, not to mention proud of his husband. He posted his own video on Instagram, and it is clear Bass was singing along with the guys, and making the audience's long-held *NSYNC/Backstreet Boys crossover dreams come true in the process. Turchin captioned his video,

God I love this guy @lancebass

Again, the swooning is way too real. Between the sweetness of Bass and Turchin, and Bass hanging out with The Backstreet Boys during their concert, my '90s pop music loving heart is very happy right now.

This is far from the first time your favorite boy band members have proven they're pals. E! News reports Bass' former bandmate, Joey Fatone, also joined the guys onstage earlier in March. Additionally, several members of both bands, as well as members of O-Town and 98 Degress, all got together to star in the Syfy zombie movie Dead 7, penned by Nick Carter in 2016.

If you are planning on catching one of The Backstreet Boys shows before their Las Vegas residency ends, you need to book your tickets in a hurry. The guys are currently set to wrap up their stay at Planet Hollywood on July 1. Seriously, given how many amazing guests have already stopped by, you can't afford to miss this astounding '90s musical event — who knows who will stop by next? (Please let it be Britney Spears.)
