Photographer Alison Jackson asked the impersonators to pose for a photo shoot. The woman posing as Middleton sits front and center amid lookalikes of everyone from Pippa Middleton to Queen Elizabeth and Camilla, Duchess of Cornwall. The women are shown making a toast as the Middleton impostor opens gifts.
A real royal baby shower isn't planned, however. Victoria Arbiter, ABC News royal expert, says Prince William, 30, and his wife "are clearly very wealthy and a lavish baby shower would be seen as highly inappropriate." The lack of a baby shower inspired Jackson's photo shoot.
Though Middleton, 31, is due in mid-July, she has already begun baby shopping. She was spotted at the Blue Almonds boutique in London last month.
