Lindsay Lohan reportedly suffered a meltdown after she was forced to foot the bill for her drinks during a night of knocking them back at Los Angeles nightspot The Crown Bar.

Lindsay is accused of refusing to pay for two bottles of champagne from the popular bar last week. The troubled actress was reportedly furious when she was given a bill for her drinks at The Crown Bar and stunned onlookers with a tantrum when staff insisted she settled her tab for her evening.

“Lindsay stormed into the kitchen and grabbed two bottles of really expensive champagne. She finished both bottles with a friend. When the bartender gave her a bill, she had a meltdown,” a eyewitness dished to PEOPLE.com. “She was yelling at him and screaming profanities at everyone. The bar insisted she pay, so she had to call a friend with her credit card information.”

The star eventually left the nightspot at 2.30am – but was still in tears over the incident. The source added: “She was crying and wanted to go home. She kept saying ‘I don’t pay for drinks! This is ridiculous! I’m freaking out!’ ”

Lindsay has caused increasing concern with her recent behavior after her estranged father Michael leaked a serious of voicemails regarding the star’s health.
