The 43-year-old Mad Men actor holds nothing back as he expresses his distaste for the 20-year-old singer. "You're like, 'What the [expletive], man?'" Hamm begins. "'What are you doing? Why?' There's no one telling these people no, and it's a shame."
Bieber has consistently made headlines in the past year for his legal and behavioral issues, and Hamm says the singer should have "a mom or dad or a really good friend who can say, 'Hey, [expletive]head!"
"You see people in the world and you're like, 'Do you know how a washing machine works? Do you know how to wash a dish?'" the actor continues. "Life skills are something we're missing...just [expletive] you needed to learn in life. There used to be a class that kids had to take in high school called home economics, which was cooking and sewing and just [expletive] you needed to learn in life."
The interview is not the first time Hamm has publicly criticized a celebrity for stupidity. The actor told Elle UK in March 2012 that, "Whether it's Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated."
"Being a [expletive]ing idiot is a valuable commodity in this culture because you're rewarded significantly," Hamm asserted. "It's celebrated. it doesn't make sense to me."
