Washington, July 13 : During the launch of her own club night, Amy Winehouse visited the loo 14 times in three hours.
All those present at the night were baffled by the 24-year-old singer's constant toilet trips.
The Rehab star went to the loo in every 12 minutes and 40 seconds and took at least nine minutes at a time.
"It was really weird," the Mirror quoted a fellow reveller, as saying.
"Amy seemed like she was on her best behaviour, keeping her head down. She was accompanied by a bodyguard and spent most of her time either texting frantically - or running back and forth to the loo," the reveller added.
According to a source, Winehouse's frantic toilet visit caused quite a commotion.
"Whenever she went to the toilets, it caused quite a commotion as people clamoured trying to take her photo or speak to her," said the source.
"But once ensconced safely inside the cubicles, she didn't emerge again for nearly 10 minutes. So when she did, the crowds once again gathered, drawing attention to her incessant toilet trips. She must have been pretty embarrassed.
"Having got a second wind from somewhere, she then went over to the DJ booth and started dancing.
"This pattern repeated itself throughout the night. But otherwise Amy was on good form, chatting animatedly to anyone and everyone," the source added.
