Lauren Conrad isn’t the only one who isn’t a fan of Spencer Pratt.

On Thursday’s Late Show With David Letterman, Mary-Kate Olsen revealed, “He used to play on the soccer team for my high school.

When Letterman asked if she thought he was “wormy,” she nodded and said, “yeah.”

“He does not have a good temper,” added Olsen, who was promoting her new indie The Wackness. “He walked out of a few games. He would walk off the field. He was like, ‘Me or the coach!’

Letterman said he was surprised by the story because Pratt looked like the kind of guy who has never broken a sweat in his life.

“Oh, my God — that brings up stories!” Olsen said. “I don’t know if I should talk about it.”

She then laughed and added, “The Wackness is a great film!”

Asked if they were friends at the time, Olsen said, “No.”

After Letterman asked her how a guy can be so “oily,” Olsen uncomfortably laughed and changed the subject.-us weekly
