Los Angeles, CA (CNS) - Lindsay Lohan has reportedly been banned from an exclusive hotel after damaging a suite.

The "Mean Girls" actress and ex-boyfriend Riley Giles spent three days at California's Shutters on the Beach Hotel and sources claim they wrecked the room.

According to reports, the couple drank the mini bar dry and left cigarette butts and dirty towels strewn all over room 645.

An insider revealed, "Staffers went into clean and were shocked. It was a pigpen. There was filth everywhere and the room stank of cigarette smoke."

Sources also claim staff found a used syringe on the bedside table.

The source added to America's Star magazine, "There was also a bloody syringe that someone left lying on the bedside table on a room service tray. Hotel security photographed it before calling someone to remove it because it was considered hazardous waste."

The hotel was allegedly forced to call in a professional cleaning crew to clean up the mess.

Lindsay and Riley - who met at Utah's Cirque Lodge rehab centre where the actress was treated for drink and drug addiction - split last month.
