Has Jon Hamm finally changed the meaning of the title of his TV show "Mad Men" to a literal one when he starts dissing Justin Bieber and referring to the singer as a "s**thead?" Because supposedly, Mad Men should not refer to men who are literally mad.

Dictionary.com states that the title is a historical term short for "Madison Avenue" men, which is coined by the show's advertising team as part of a promotional strategy. Hamm plays Don Draper in the show since 2007 up to present, and seven years of being on the show has put him in a pedestal with a definite label.

However, Jon Hamm seems to have recently blurred the lines that separate Mad Men from its "supposed" meaning to its "literal" meaning of the title.

In his latest interview with Men's Fitness for its May issue, the 43-year-old actor is said to have revealed a different side of him totally far from his womanizing advertising executive Don Draper character. According to the publication, Hamm "bears none of the arrogance and boorishness" of Draper in person. So dissing Bieber does not count?

"Look at Bieber or whoever," Hamm says in reference to the 20-year-old pop star. "You're like, 'What the f--k, man? What are you doing? Why?' There's no one telling those people no, and it's a shame."

And the Golden Globe winner added that Bieber should have "a mom or a dad or a really good friend who can say, 'Hey, s**thead!'" According to an Us Weekly report, Hamm is clear that he is not a "Belieber."

"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 s--t 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 s--t you needed to learn in life."

Bieber has yet to comment to Hamm's statement, the report says. However, the pop star has posted on his Twitter account regarding his current status, which is obviously not in for any revenge.

In a happy place. Much love to everyone this Easter

Apparently, Justin Bieber is also excited for what may be in store for him. The 20-year-old pop star appears to be embracing change through his recent post on Twitter.
