Winehouse's services sought by Clooney and Roberts

Amy Winehouse is on the verge of a massive career and financial boost courtesy of George Clooney and Julia Roberts - who have been assigned to recruit the troubled singer for an exclusive New York event.

Party host and fashion designer Giorgio Armani has asked the Hollywood pair - who are co-chairs at the Metropolitan Museum of Art Costume Institute, where the event will be held on 5 May - to offer the 'Back To Black' star $1m (€634,000) to perform.
