After bashing her and calling her a "troll," Spencer Pratt has apologized to Mary-Kate Olsen for his outburst.

Last week, Olsen had told David Letterman on his talk show that Pratt used to play soccer in their high school. She revealed that the reality TV actor had a short temper and would often walk out of the game.

As expected, Pratt immediately launched an attack at the pint-sized industry mogul.

He told Us magazine, "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."

Now, in an attempt to explain himself, Pratt is taking back the bad things he said about Olsen.

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

"I know Dave was just doing his job in asking her. He's the best in the game at that."

He also confessed that he "respect Mary Kate as a businesswoman" and that he is "secretly jealous of her. I want my face on a lunchbox, too!"
