It sounds as though Lindsay Lohan is seriously running low on her cash supply.

The troubled Tinseltowner was spotted all-smiles at Hollywood hotspot Crown Bar last Thursday but suddenly left in tears -- apparently before paying her bills.

Pop Tarts has been told that toward the end of the evening, Lohan ordered a bottle of champagne but when approached her for the bill she wasn't prepared to pay up.

“Lindsay pointed over at Kellan Lutz and told the waitress just to charge his card,” an insider said.

Lohan left soon after and apparently the situation wasn't really resolved. Naughty naughty.

A rep for Lindsay did not respond for comment.

But unpaid bottles of champagne is probably the least of Lindsay’s worries right now considering more and more leaked telephone conversations concerning her are hitting the worldwide web.

In a taped argument between parents Dina and Michael Lohan in 2008 (released by Radar Online), Dina reveals that Lindsay’s situation is “bad” and that she's “cutting herself and hurting herself.”

To add insult to injury, big-wig fashion designer Emmanuel Ungaro re-enforced to the crowd at the Astor Film Festival in Lisbon earlier this week just how big of a “disaster” Lohan's recent debut during Paris Fashion Week truly was, adding that the collection made him “furious.”

But no matter how much chaos and negativity surrounds Lohan's personal life and no matter how much she pouts when she sees the paps, she just can't seem to stay out of the spotlight for a single night. Lohan chose to hit up one of the hottest spots in West Hollywood on Wednesday night, Cecilia, to have dinner with a friend.

Note to Lindsay: There is such thing as take-out!
