Kate Middleton really, really loves her polka dot Topshop dress, Ralph Lauren blazer and Episode "Angel" pumps. After wearing the ensemble during a Warner Bros. Studios tour in late April, the pregnant Duchess of Cambridge wore the same look for her friends' wedding in England on May 11. She did change things up slightly, however, as she donned a new fascinator.

The first-time mom-to-be and her husband, Prince William, were seen driving in a Renault Clio en route to Ewelme, a small town in South Oxfordshire. They watched with glee as William van Cutsem and Rosie Ruck Keen tied the knot. The bride and groom's ceremony took place in the Ewelme Parish Church, which dates as far back as the 15th century.

Middleton, 31, has been friends with the van Cutsem family for years. She attended Rose Astor's wedding to Hugh van Cutsem in 2005, and six years later, their daughter Grace served as one of Middleton's flower girls during the royal wedding.

Prince Harry, meanwhile, recently began his tour of the United States. Since his arrival on May 9, he has spent time with Vice President Joe Biden, First Lady Michelle Obama and Olympic gold medalist Missy Franklin. The 28-year-old royal has also met with wounded war veterans while making pitstops in Washington, D.C. and Denver.
