Born – July 2, 1986
New York, New York, U.S.

Actress, singer, train wreck, hopefully actress again.

Starred in remakes of "The Parent Trap" and "Freaky Friday," went on to make "Mean Girls," then went on to make a lot of mistakes, but very few actual movies.

Was friends with Paris Hilton, stopped being friends with Paris Hilton, was called a "fire crotch" by Paris Hilton’s BFF Brandon Davis.

Dated DJ Sam Ronson in 2008 and 2009. And by "dated," we mean they were just good friends who hung out and went shopping and in no way engaged in hot hot girl-on-girl action, possibly with tickling and pillow fighting.

Has had one or two little personal problems, which include the following (deep breath):

Crashed her car, went to rehab, got arrested for driving under the influence, went back to rehab, got arrested for driving under the influence again, went back to rehab, went to jail for five hours, served house arrest, got into a fight with a worker at the Betty Ford Clinic, stole a necklace (allegedly), failed a drug test, wore an alcohol monitoring ankle bracelet, appeared in court nine times in 10 months, and worked at the L.A. County morgue. Oh and posed nude for Playboy. We can't forget that.

Seems to be OK now, but that could change by the time you're done reading this sentence.

Fun fact: Has a twin sister that no one ever heard from again after "The Parent Trap" was released.
