Kelly Rowland spent almost $400,000 on a night out.
The former Destiny's Child singer racked up a $372,680 bar bill on guests - including U2 frontman Bono - at Amika's Weekend Takeover in St. Tropez, France, on Friday.
A source revealed: "Kelly was the ultimate host and even when the bar bill began to spiral out of control she didn't close the tab."
"At one point Kelly started dancing and put on a silly hat, which made everyone laugh. "Bono arrived quite late and Kelly told him to order whatever he wanted."
The 10-hour drinking session saw 30 revelers drink 50 magnums of vintage Dom Perignon champagne, costing $6,000 each, 24 bottles of tequila at $930 each and 10 bottles of $4,000 cognac.
St. Tropez is a favorite holiday destination of many stars. As well as Kelly and Bono, "Closer" singer Ne-Yo and supermodel Naomi Campbell have been seen holidaying there in recent weeks.
