Spencer Pratt Apologizes to Mary-Kate Olsen

Hoping to put an end to a brewing (and hilarious) celebrity feud, Spencer Pratt is apologizing to Mary-Kate Olsen for calling her names.

Specifically, he called M-K "the less cute Olsen twin."

After Olsen told David Letterman how The Hills star used to throw temper tantrums during their high school soccer games, Spencer Pratt responded with a tirade statement to celebrity news magazine Us Weekly. Now he's sorry, though.

"I apologize for getting caught up in trash talking, but she brought up an emotional subject when she mentioned the soccer stuff," Pratt said.

"I know [David Letterman] was just doing his job in asking her about it. He's the best in the game at that."

Spencer Pratt even admitted he is envious of Mary-Kate Olsen.

"I respect Mary Kate as a business-woman," he said. "I'm secretly jealous of her. I want my face on a lunchbox, too!"

Apparently, the bad blood between the two began after Spencer sold photos of Mary-Kate drinking underage to Star magazine while in high school.
