The Backstreet Boys performed during the VMAs preshow, 20 years since making their debut at the show in 1998. Inside, they hit the stage again to present an award, and gave fans a bit of that old boy band razzle dazzle by playfully harmonizing the nominees' songs. Full disclosure: I'm an *NSYNC girl. But BSB's appearance was still a nice way for MTV to give an older millennial like me a thread to her pimply, lovestruck teenage past.
