Kate Middleton & Prince William: Harry Potter Wand Battle!

Catherine, Duchess of Cambridge (aka Kate Middleton) and Prince William have a wand battle while visiting the Harry Potter sets during a visit to Warner Bros. Studios Leavesden on Friday (April 26) in London, England.

The 31-year-old pregnant royal and the 30-year-old Duke of Cambridge were joined by his younger brother Prince Harry as they officially opened the studios and met with senior executives.

In addition to the Harry Potter sets, the royals also viewed props from The Dark Knight trilogy.

FYI: Kate showed off her baby bump in a Topshop dress and a Ralph Lauren blazer.
