Jon Hamm has a few things about Justin Bieber and the rest of young Hollywood — and they’re not pretty words. Appearing on the cover of Men’s Fitness magazine’s May issue, the Mad Men actor blasts the pop star for his infamous wild ways. “Look at Bieber or whoever,” he says. “You’re like, ‘What the f, man? What are you doing? Why?’ There’s no one telling those people no, and it’s a shame.” The 43-year-old goes on to blame the lack of parental supervision and the “yes man” entourages these stars travel with. And Bieber isn’t really proving Hamm wrong these days. Between not knowing where to pee and getting arrested for a DUI, the young singer is certainly doing a great job of proving him right.
