On this episode of 'When I Was 17,' we take a look back on the teenage years of Khloe Kardashian, Perez Hilton and Trey Songz. For reality star Khloe Kardashian, there was never a dull moment when she was 17 -- from stealing her mom's car to passing out during Tae Bo to impersonating a professional stylist. In Miami, a young Perez Hilton was working at a department store and raising money to travel to Spain, all while looking up to his hero Madonna. And in Virginia, R&B crooner Trey Songz was keeping busy by being his friends' trusted barber and going to multiple proms with different girls.
