So Justin Bieber posted a photo of him reinacting a famous shot of James Dean on Instagram over the weekend. For fear anyone may have missed the comparison, he then posted a photo of James Dean a day later. He's helpful like that.
He also felt obliged to point out that he doesn't smoke (cigarettes). The below photo bore the following caption: "This is James Dean inspired. Don't ask me if I smoke ciggys cuz I don't"
Personally, I don't see the resemblance apart from the props. Now, if he'd posted a photo of Tanita Tikaram, he's got that look nailed without even trying.
