John Shearer/WireImage.comNothing we like better than a feud between a couple of our favorite fame wisps. So we're digging it that Hills hunk (of something) Spencer Pratt is bashing back at Mary-Kate Olsen:
"I know I've made it in Hollywood when a famous troll is talking about me on Letterman," Pratt said in an interview.
You may recall that Mary-Kate told Dave that Spencer had a bad temper in high school and agreed with Letterman that Spencer is "wormy." (If you missed M.K.'s diss-a-thon, no worries, check out the clip below.)
Trying unsuccessfully to squirm away from the wormy label, Pratt also told Us Weekly that Mary-Kate "should probably focus more on not getting dressed in the dark than on me."
Continuing on in his vehemently vermicular way, Spencer feigned taking the high road:
"I forgive her, though. She's had to go through life as the less cute twin, which must be tough."
Nice! There are lots of ways to be less cute, and Pratt seems to have mastered them all.
