On Sunday night, the former actress, 27, told Oprah: "There's no party that I haven't gone to, there's no person that I haven't hung out with, there's no situation that I haven't been exposed to." And she insisted: "There's nothing left in having a drink for me."

But she must have found something to occupy herself at LA's famous party venue the Chateau Marmont, as I can reveal she was there until 5am on Saturday morning. And something kept her amused enough to go on to a house party. She can't be too done with fun times, because she was back partying at the hotel later that evening, too - and she remained there until the early hours of Sunday morning.

I'm told: "Lindsay started on Friday night at the cocktail bar at the Beverly Hills hotel, before moving on to the Chateau. She was out in the garden until early in the morning, and then the group moved on to a house party in the Hills. Literally hours later she was back in party mode at the Chateau again."self.
