Lindsay Lohan's Rehab Boyfriend Still Dating Actress: Lindsay Madly In Love With 23-Year-Old Patient?

Lindsay Lohan had a secret rehab boyfriend and is still seeing each other after she had been released from the Cliffside Malibu treatment center. A former patient told RadarOnline Lindsay started a romance as soon as she arrived at the rehab center, "Prior to Lindsay's arrival I was roommates with the guy who ended up dating her. When she came, the first or second day they ended up kissing and it was on from there."

The source added, "The guy was actually dating someone else in rehab at the time and Lindsay told him he needed to get rid of that other girl and be with her only. She was really territorial with him."

Once the clinic found out about the relationship, the center decided to excuse Lohan's love interest, "Everybody in rehab knew they were dating. It was pretty obvious. But the guy eventually got kicked out because of Lindsay." the source said.

The source continued to tell RdarOnline,"The guy who owns Cliffside slacked on the rules for Lindsay, but they got cocky with their relationship and people got uncomfortable with the situation, saying they couldn't do that stuff when people are trying to get well. It was the Lindsay show. Drama."

Adding, "I know that's why he was asked to leave, because Cliffside made a big scene about it. They interviewed everyone about it, and all the girls ratted them out because they hated Lindsay."

Lohan, 27, is still seeing the 23-year-old male patient, "They're still together now. They go to meetings outside and she meets him there. She still talks to him every day," the insider confessed, "He was at my house in Orange County on July 4th and Lindsay was totally controlling him, calling him saying she was going to get a car to pick him up or something because she wanted to see him. It was crazy."

Hmmm, is a relationship best with someone that has the same issues as you?
