What’s Mischa’s Line?

I guess they had cue cards on The O.C.

According to RadarOnline, Mischa Barton is causing trouble on the set of Law & Order: SVU.  Barton is filming a guest spot on the show, in which she is playing a prostitute. 

From the photos I've seen taken from the set, she just has to dress poorly and suck on a lollipop.  It seems a little on the nose. 

But apparently Barton cost the production a lot of money when they shot a scene that took much longer than planned, because she kept screwing up and couldn't remember her seven lines.
