My friend thinks that the girl who justin cheats with (the brown haired girl, not britney) is Lacey Chabert, the girl from party of 5, and not just another teen movie. I dont think that it is her. I want to know who the actress is. Can anyone tell me either who this girl is and/or where I can find this info? Write me at sawolf@indiana.edu or reply to this message. Thank You. -Steve
