Mischa Barton was kicked out of a ladies' bathroom at a London club after trying to bring her pal into one of the cubicles, reports the Daily Mail (UK).
The former OC waif and current star of The Beautiful Life, 23, was at Whisky Mist nightclub in Mayfair when she decided to drag a friend into the can.
A spy said: "Mischa looked like she was having a good night. After sitting with a few pals at her VIP table she dragged her friend Bridget into the loos."
For a little girl-on-girl action, maybe?
The source continued: "They tried to go into the toilet cubicle together but they were stopped by the toilet attendant. The lady said to her, "What are you doing? You are not allowed to go in together, you have to come out now."
"Mischa looked really p***ed off and embarrassed but her friend was fine."
Despite a long line, Mischa Barton then decided to go into another cubicle alone - but her night didn't get any better. She apparently took so long that the attendant was forced to check if the actress was feeling okay.
Not eating for a couple of weeks often leaves her woozy.
An onlooker said: "She took so long to emerge that everyone was worried about her. At one point the toilet attendant had to knock on her door twice to ask if she was alright. Then her mate was knocking to check she was feeling okay."
"When she came out of the cubicle, she was complaining about people knocking on the door. She looked slightly worse as she attempted to apply her make-up."
Mischa was with five pals and her rumored beau Noel Fielding at that venue most of the evening before calling it a night at 2:30 and heading to another club.
