JENNIFER LOPEZ - ANTHONY WRITES 'F**K YOU' ON CHARITY CHEQUE

JENNIFER LOPEZ's third husband MARC ANTHONY stunned hotel guests and staff by refusing to draw a sketch for a charity auction - instead writing 'F**k You' on his slip of paper.

The high-profile couple were in New York attending J.Lo's Bryant Park fashion show after-party in W Hotels' VIP hospitality suite.

Celebrities who attended the event - including actress ELISHA CUTHBERT, comedian JOHN LEGUIZAMO and designer and socialite CHARLOTTE RONSON - were invited to draw caricatures of themselves to be displayed at W Hotels properties and later auctioned off for charity.

But Anthony stunned hotel staff by refusing to participate, instead scrawling his shocking profanity.

A source says, "Everyone was drawing caricatures, doing their little drawings and stuff to be framed.

"They handed a piece of paper to Marc, for either him or J.Lo to draw on.

"He wrote 'F**k You,' and passed it back. People were totally taken aback.

"And now the other art is touring, and they literally have his 'F**k You' in storage."

The paper slip is currently sitting in the basement of the W Hotels headquarters in the Chelsea district of New York, and local newspaper the New York Daily News predicts it will soon appear on internet auction site eBay.
