'Hills' star apologises for Olsen jibe

Spencer Pratt from US reality TV show The Hills has apologised to Mary-Kate Olsen for remarks made about her looks.

Olsen, a former schoolmate of Pratt, revealed on The Late Show With David Letterman that he was a star soccer player in high school with a short temper on the pitch.

Pratt then hit out at the actress, calling her "the less cute Olsen twin".

The 24-year-old has now taken back his comments, telling Us Weekly: "I apologise for getting caught up in trash talking, but she brought up an emotional subject when she mentioned the soccer stuff.

"I'm secretly jealous of her."
