kim-k-fat-kris-mean.jpgWe just learned that Kris Humphies is reportedly suing estranged wife Kim Kardashian for $10 million, and now sources close to the reality TV starlet are dishing the dirty deets on what a horrible spouse the NBA star was.

In the cover story titled "Husband From Hell," a pal tells Us Weekly, "[Kris] belittled her in front of people. He'd call her stupid. It was truly sickening." According the the mag, Kris also criticized Kim for her full figure, calling her "fat a**." Ouch!

Kim filed for divorce less than a month ago, and even though Kris claimed he was "devastated" by the news, sources close to Kim revealed that the two were constantly fighting about everything from money to her celebrity status.

And that's not all! "He tried to control Kim by bringing her down," the source continued. "He would say truly terrible things. One time, he said she had no talent and her fame wouldn't last."
