Wyclef Jean can even get European royalty to its feet. The star performed at a packed dinner hosted by David Hryck for Britain’s Prince Edward at the Core Club on East 55th Street the other night. Guests included Petra Nemcova, Colin Cowie, Georgette Mosbacher, Catherine Saxton and Dr. Ruth. A spy said, “The guests behaved like kids at a rock concert. Wyclef gave an impassioned plea for more help for his people in Haiti, then wowed the crowd with his performance — and the ability to play a guitar with his tongue.”
