The Duchess of Cambridge caused quite a stir earlier this week (though not as much as other royals have). Kate Middleton arrived at the Photographer of the Year Awards donning a light blue dress and cream peep-toe pumps — a fashion choice that has led to some debate on social media.

Check out other A-listers who have made sky-high heels part of their maternity attire.
