Britney Spears and Melissa Joan Hart brought back all the TGIF/teenybopper feels this week when the ladies reunited briefly backstage at the pop princess’ Piece of Me Show in Sin City. The old friends also gave each other shout outs following the show. The pair first met in 1999 when they filmed a music video for “(You Drive Me) Crazy” from Hart’s film Drive Me Crazy. Spears also guest-starred on Sabrina, The Teenage Witch.
