With this year's MTV VMAs this weekend, we're looking back on one of the most memorable VMAs performances of the '90s — the time a young Britney Spears shared the stage with *NSYNC. After a classroom roll call, Spears opened with a dance-filled take on ". . . Baby One More Time." As her performance ended, a curly-haired Justin Timberlake joined his *NSYNC bandmates on stage for a dance routine and "Tearin' Up My Heart." Watch the full VMAs performance above, then check out a behind-the-scenes snap from rehearsals below.
