Lindsay Lohan's BlackBerry has been hacked! The rollicking redhead was horrified to learn that an unknown party was sending lewd and nasty messages to her pals while making it look like they were coming from Lindsay. The New York Post's PageSix reports that her lawyers on are on the case and are even suggesting that Paris Hilton, her famous rival, may have had something to do with the incident. According to Lindsay's rep, Leslie Sloane Zelnik, "some people think Paris may have been involved because the wording of the messages sounds very familiar." Paris' reps deny her involvement.
