Pop star Prince was left red-faced on Friday (23Aug13) when he forgot to stock up his wallet with cash and was unable to pay his bill at a top New York restaurant.

The Purple Rain hitmaker headed for a meal with a pal at chef Michael White's Costata eaterie but when it came time to settle the bill, he realised he had no money with him.

A member of Prince's security team eventually explained the embarrassing mishap to the restaurant manager, who agreed the singer could settle the debt the following day, according to New York Post gossip column Page Six.
