Now that's how you kick off an award show! Ahead of the MTV VMAs on Monday night, Backstreet Boys set the mood by giving a high-energy performance during the preshow. The '90s boy band [1] made us swoon with their incredible vocals and choreography as they sang their hit song "Don't Go Breaking My Heart [2]" on top of Radio City Music Hall. The performance marked 20 years since the band made their debut at the MTV VMAs [3] in 1998. Suddenly, we feel like lovestruck teenagers all over again. See their performance ahead.
