George Clooney has sparked rumors he has rekindled his romance with Lisa Snowdon - after she attended his latest film premiere. The Hollywood bachelor, who has had an on-off relationship with the British model, turned up to the London screening on 'Good Night and Good Luck' alone.

But just moments later, stunning Lisa arrived at the Leicester Square cinema, claiming she was there to "support a friend." The couple called time on their year-long relationship in May after deciding their long-distance romance had run its course.

Sources claimed living apart - TV presenter Lisa lives in England while the 'Oceans Twelve' actor is based in Los Angeles - put too much strain on the relationship.

A friend said at the time: "It's always difficult to maintain a long distance relationship. They spoke on the phone regularly but they began to realize that the relationship had nowhere to go." Beautiful Lisa, 33, had already ruled out a move to LA to be with her lover, insisting: "I would miss Britain too much." Since his split from Lisa, George has been linked to his other on-off girlfriend Krista Allen and Italian heiress Gianna Elvira Cantatore.
