Sebastian Karnaby, a pharmacist, tells Page Six he was trying to leave the party for the Times’ T style magazine at the hotel’s new Boom Boom the other night when he had the encounter with Love.

He said, “I couldn’t find my way out and asked someone to show me the door.” He opened the door he was led to, and “there was Courtney Love, sitting on the toilet with her skirt around her ankles.”

Karnaby says he was shocked and slammed the door shut, but that wasn’t enough for Love. He relates, “She stormed out screaming, ‘I am going to get you thrown out!’ She jumped on me, went crazy and dragged me over to security by the arm and claimed that I’d attacked her. They were trying to calm her down, but she was out of control. She was like a possessed woman. I absolutely did not attack her — I was trying to get away,” Karnaby said. “Thankfully, she’d remembered to pull up her skirt.”

He says security told him, “It’s best you get away as fast as possible. I never wanted to see Courtney Love on the toilet,” he said. “It wasn’t a pretty sight. I just wanted to get out of there.”

“Courtney has been struggling with her weight. She’s been using the hormones to help her gain muscle and for anti-ageing and likes the results. But she’s not very discreet. She even left a vial of it in her LA hotel room.”

Trainwreck Courney Love is being sued by American Express.  Courtney reportedly “failed and refuesed,” to make payments on her AmEx Gold Card, racking up an a$$load of purchases in excess of $350,000.  Must be nice to buy things and not want to pay them back.  The U.S. District Court will be handling the suit.  Ya know, you’d think after all the trouble she went through to collect on Kurt Cobain’s money she would at least pay her damn bills.  Crazy a$$ b*tch!
