Most people wonder what their favorite celebrities were like when they were teenagers. MTV's hit show "When I Was 17" reveals all the hidden embarrassing secrets of your favorite celeb when they were just 17 years old. 

Before UK singer Jessie J rocketed to fame, she was a focused, confident singer who loved Kanye West. Surprisingly, Jessie J was also a nail technician who loved to draw all sorts of cool nail art on her customers' nails. 

Before Lupe Fiasco was an outspoken, no bullsh*t rapper, he was a nerdy kid who played chess daily and who mastered the art of fighting with karate. Rapping was always Lupe's priority, but he still made time for riding on his beloved skateboard.
