In 1989, Madonna empowered women with "Express Yourself." It was also the year Taylor Swift was born. Despite their age difference, it turns out Taylor Swift is a big Madonna fan, and the junior singer couldn't help but show it during the Grammy Awards on Sunday. As Madonna belted out her new single "Living For Love," Taylor sang along and danced in the audience, but things got even cuter when they hugged backstage. "Madonna is now a person I've met. #TheGrammys," Taylor tweeted afterward.
