On August 28, 2003, the VMA's were hosted at the Radio City Music Hall in New York City. To open the show, Britney Spears and Christina Aguilera performed together Madonna's classic hit Like a Virgin, and were later joined by Madonna herself to perform Hollywood. In the middle of the performance, Madonna kissed Britney and then Christina, going down in history as one of the most iconic moments of the VMA's and awards shows in general. Missy Elliott then appeared onstage to perform her song Work It, and then the four together will close the performance with Hollywood again.
Sadly, MTV's YouTube channel has made the official video private amid the upcoming 2020 ceremony, so here's another low quality version of the performance:
Britney also had a nomination that night for Best Video from a Film, for Boys (Co-Ed Remix) ft. Pharrell Williams, but lost to Eminem's Lose Yourself.
