Lindsay Lohan's love life may be blossoming but that hasn't stopped her troubled past coming back to haunt her, according to a new report.

According to a U.S. publication, the actress has started cutting herself again, and is back on the drink and drugs.

“Lindsay has a very addictive personality, and her drugs of choice are cocaine and prescription pills," an insider tells Star.

“She has different dealers in L.A .and New York. Half the problem is that nobody says no to Lindsay.”

Lindsay's family are said to have become concerned for her health after shocking images taken at the Video Music Awards appeared to show red scratches running along her arms.

The source adds, “Lindsay has locked herself in the bathroom and cut herself in the past. Sam is aware of this and has hidden razors from Lindsay.

“Her parents found out that she was hurting herself again about two months ago and even started planning an intervention. But it never took place because Lindsay got wind of it and her mom, Dina, backed down.”

Lindsay spent two stints in rehab in 2007 in an attempt to conquer her demons.
