Mary-Kate Olsen has earned a new enemy in Hills star Spencer Pratt after The Wackness star called her former high school classmate out on his “bad temper” during appearance on the Late Show with David Letterman on Thursday night. (Video Here)

MK told David that Spencer played soccer at her high school where he routinely behaved like an uppity asshat. (Which isn’t that hard to believe.) “He does not have a good temper. He would walk off the field.”

Spencer has come out swinging. The reality personality has instructed Mary-Kate to shut her piehole in a insult-riddled statement to Us Magazine:
“I don’t really get why she’d use my name to get press for her little indie film that no one’s going to see. She should probably focus more on not getting dressed in the dark than on me…..I know I’ve made it in Hollywood when a famous troll is talking about me on Letterman. I forgive her, though. She’s had to go through life as the less cute twin, which must be tough.”

(Note to Spencer: Your bitter tone was very helpful in disproving Olsen’s observation that you’re a complete douchebag.)

Someone who’s engaged to marry a walking billboard for cosmetic surgery has got a lot of nerve calling anyone a troll. Heidi Montag’s about one eyelift away from becoming Joan Rivers. At least Mary-Kate’s still has her nose.
