Justin Timberlake started out as a Mouseketeer on the Mickey Mouse Club along with several other famous people like Britney Spears, Christina Aguilera, Ryan Gosling, JC Chasez and others.  In an appearance on the Ellen Degeneres show scheduled for tomorrow, Justin describes what he and Ryan Gosling did one day while on the MGM Studio lot as mouseketeers right after the jump.

Justin admits to Ellen in the clip below that he and Ryan "used to do terrible things!"  Find out what those terrible things are now...
