Lindsay Lohan's pursuit of 18-year-old model Morgan O'Connor seems to have ended unsuccessfully, as O'Connor has reportedly told the troubled starlet to take a hike, according to Radar Online. "When he first started hanging around Lindsay, she was totally chasing him and everyone was telling him not to go out with her because she is white trash and would bring his career down," a source says. "But he had a good time with her and got to go to a lot of parties that he wouldn't have been able to go to before. Now he realizes that he can't hang out with Lindsay and he basically dumped her and is trying to commit to his girlfriend again." As a clear sign of that change of heart, O'Connor recently had the name of ex-girlfriend Chiara DiGiallorenzo permanently applied to his body. "Morgan has always really loved Chiara, and he tattooed her name on his arm to prove that," the source says.
