Lindsay Lohan's ex-boyfriend Riley Giles has spoken out and he is basically saying that Lindsay has a very addictive personality. He says that she replaced drugs with sex while in rehab. And after rehab she replaced the sex with shopping, tanning and eating.

He says: "Lindsay's definitely a nymphomaniac. She's wild in bed. We'd have sex a couple of times in the day and then go to it through the night.

"We once did it four times in a row straight. That was crazy. Lindsay was insatiable. She'd demand sex again and again. We'd go at it for hours. She'd have worn out most guys."

He says that the two hooked up when Lindsay passed him a note asking for his number. After that she basically attacked him and the rest is history. He says that she was a different person in Utah. She even wanted to buy a place out there and stay away from the limelight. Unfortunately, that all changed when she came back to LA.

"I worry because it must be very difficult to keep up your recovery," he said. "I couldn't do it. Lindsay has a very addictive personality.

And now she's switched habits again. First it was drugs, then it was sex, now it's shopping. Her whole day consists of spending—EVERY day. She gets her hair done every day and has a spray tan twice a week. I don't think it's healthy."
