While watching a group of teenagers on the Mickey Mouse Club way back in 1993, nobody would have guessed that four of them, Justin Timberlake, Britney Spears, Christina Aguilera and Ryan Gosling, would be superstars two decades later. It just happened. Following the foot steps of the former which got big along with N’Sync boys band, the two blonde girls both arrived in the Pop Music scene in 1998 / 1999 with a huge #1 hit, instantly drawing attention and creating the perfect rivalry story for gossip magazines.
