Kate Middleton's five different dresses

The Duchess of Cambridge will wear FIVE different outfits on Christmas day with the Royals.

It's the first time Kate will be with Prince William and his family for Christmas, following their world famous wedding back in April.

Kate let the bizarre dress code slip to a guest at the recent 'Millies' awards, which celebrate the brave men and women serving in our armed forces.

Sheridan Bowler, the partner of a nominated marine, told The Sun: "She said she was looking forward to Christmas with Prince William's family, and said she had to change dress five times on Christmas Day. I couldn't believe it."

Meanwhile, Kate and Will visited a homeless centre last night (December 21st) in South London, chatting to youngsters at Centrepoint's Camberwell Foyer.

Kate giggled as Will joined in a dance routine and the Duke and Duchess of Cambridge also joined in a 'healthy living cookery session'.
