So does this mean Justin Bieber is officially changing his tune?

Bieber, 21, graces the cover of Seventeen magazine's summer issue.

"I was rebelling a little bit," Bieber told Seventeen. "I was getting cockier and cockier. I didn't have people to check me. I looked back and I was disappointed in myself."

That's big of Biebs to admit!

"I always want to be honest and let people know that those mistakes aren't who I am," Bieber said. "Who I am is someone who really cares about people."

Well, that's good and all, but what did he have to say about love? And what does he look for in a girl?

"I need healthy relationships with people I can feel safe with," Bieber said. "In a girl, I want someone who's confident in herself and honest. I have to find her very attractive and as someone I can see myself with for the rest of my life."

LOL. Someone who is "very attractive" and "honest." Don't we all, Biebs?
