"I was rebelling a little bit," Justin explained of his bad boy antics. "I was getting cockier and cockier. I didn\'t have people to check me."

While he admits he didn\'t always have the best role models, he\'s owning up to his mistakes — and proving his very public apology tour is much more than just a publicity stunt.
