Prince Harry has sparked rumors that he is back in the arms of his ex-girlfriend, Chelsy Davy, after they both attended a birthday party for Princess Eugenie on Friday night.

Prince William's fun loving brother and his blonde bombshell spent the night chatting at the intimate dinner at Windsor Castle to celebrate his cousin's 22nd birthday.

But the next night, Harry was out clubbing with a pack of friends, and no sign of Chelsea, so the status of their relationship is still something of a mystery.
