Local Singer Learns France is Not Ecstatic

Memo to Jimmy: don't leave the stuff in your luggage.

French authorities reportedly seized more than 100 tabs of club drug "ecstasy" from Jimmy Buffett's luggage this week.

The Grammy-winning singer got into trouble when he flew into Toulon-Hyères International Airport in the South of France on a rented private jet and customs officials started poking around in his suitcases. According to local press reports, they uncovered more than 100 tablets of the mind-bending substance.

Buffett, who was on his way to chill out in the ritzy resort town of St. Tropez, was detained, but not arrested, and allowed to go free after paying a fine of 300 euros - about $380. That prompted one local newspaper editorial to term the slap-on-the-wrist punishment "a small amount for a man who makes $70 million a year."

A spokeswoman for Buffett - whose hits include "Cheeseburger in Paradise" and "Why Don't We Get Drunk" - denied he'd had any ecstasy in the luggage. The rep insisted, "It was medicine prescribed by his doctor." But she wouldn't name the medicine or what ailment Buffett was using it for.

We know it was NOT Margarita-mix.
