Britney Spears and Justin Timberlake

Before Britney Spears and Justin Timberlake became a couple, and before they became worldwide sensations for their musical success, they were just a pair of childhood buddies.
In 1993 and 1994 — along with future pop stars Christina Aguilera and JC Chasez — Spears and Timberlake were cast members on The Mickey Mouse Club. In 1999 their friendship blossomed into a romantic relationship, staying together until 2002.
