Anne Hathaway begged Italian fashion designer Valentino Garavani to autograph her dress - after he accidentally spilled red wine all over the gown.

The Devil Wears Prada star was at a private dinner for the 76-year-old in New York on Tuesday night, which saw Gwyneth Paltrow and Madonna turn out for the style mogul.

Valentino was greeting his guests at the party when he knocked his glass of wine over Hathaway's frock.

But instead of getting worked up about the incident, Hathaway laughed off the spillage - and even asked the fashionista to sign the stained garment.

An eyewitness tells the New York Daily News, "Anne was covered in wine, but she laughed about it. She told him, 'I want you to autograph this dress and sign it right now.'"
