Star's harsh words about Kardashian, Hilton

Jon Hamm usually steers clear of controversy, but not anymore!

In the April issue of ELLE UK, the Mad Men actor, 40, complains: "Whether it's Paris Hilton or Kim Kardashian or whoever, stupidity is certainly celebrated. Being a f-cking idiot is a valuable commodity in this culture because you're rewarded significantly."

The idea that reality stars can create successful businesses "doesn't make any sense" to Hamm, who also tells ELLE UK he doesn't' "even consider myself handsome."

Like it or not, Hilton and Kardashian, both 31, have created lucrative brands after becoming two of the world's most photographed women.

"I'm involved in my products every step of the way. My fragrances are doing really well at the moment," Hilton told FHM UK's in January. "They've produced more than $1.3 billion in revenue since 2005."

Kardashian and her famous family, meanwhile, earned a collective $65 million in 2010 alone. "It's annoying when I hear, 'What do your girls do?' Well, first of all, all of my daughters have jobs. They are fashion stylists and designers; they own a chain of stores. They had the stores before they had the show," her mom Kris Jenner, 55, told Redbook in May 2011.

"And my kids worked from the time they were 13 years old. So to me, that's a huge misconception that the girls don't work," Jenner added. "They work 25 hours a day."
