Justin Bieber: 'I'm a Pretty Sensitive Guy'

Justin Bieber gets silly as he stops by SiriusXM Hits 1′s The Morning Mash Up at SiriusXM Studios on Thursday (August 27) in Los Angeles.

The 21-year-old entertainer, who is getting ready to drop his new single “What Do You Mean?”, recently opened up about mistakes he’s made during a talk with Z100′s Elvis Duran.

“Would I do anything different? I would probably stay away from Miami,” Justin said (via Us Weekly). “Trusting people is hard, especially for me. I’ve trusted people who I probably shouldn’t have trusted before and they’ve hurt my heart. I’m a pretty sensitive guy, so I’ll lay it all on the line, and they’ll kind of pull it. So now I’m figuring out there’s certain people I can’t do that with.”

Justin added, “There’s so many beautiful and amazing people who will encourage you, who will love you, who will not judge you. But I didn’t see that because I completely put myself over here. I still have moments where I’m like, ‘Yeah people suck.’ And then I’ll have those moments of like, ‘No, people are awesome, and this is why I do what I do in the first place.’”
