Their storyline on The Hills might be a little dry, but the real background of reality star Spencer Pratt and his sister Stephanie is way juicy. Today, our brother site Gawker reports that Spencer may have hired a "tutor" to write his college essays while he smoked dope and popped Xanax. Now Star is reporting that Stephanie — the "She Pratt" we were introduced to on last night's episode — has a criminal background. (That's her mugshot there on the left.) It seems that in May 2006, Stephanie — then 20 — was arrested in Hawaii with a friend, who happens to be the daughter of a production exec of the ABC series Lost. The girls had shoplifted more than $1,300 worth of clothing from Neiman Marcus. They were charged with second-degree theft and taken to police headquarters, where they both said they were on prescription medication. After searching the girls' bags, the cops found some really fun stuff.
