Prince William, Duke of Cambridge threw a bash at Windsor Castle on May 13 to network with high-profile showbiz guests such as Kate Moss, Emma Watson and Benedict Cumberbatch. He was seen especially bonding with Harry Potter star Emma Watson, even as his wife Kate Middleton (Duchess of Cambridge) was at home with baby Prince George.

But people present at the ball have reportedly said that more than the young Emma, it was Kate Moss who ‘flirted’ with the older son of the late Princess Diana and Prince Charles.

Check out a video of some celebrity pictures from Prince William’s gala dinner at the Windsor Castle, organised to celebrate the work of The Royal Marsden Hospital of which the prince is president.
