Meghan Markle makes surprise appearance at Wimbledon to cheer Serena Williams to victory (photos)

The Duchess of Sussex was joined by two old friends at Wimbledon yesterday as she made a surprise appearance to cheer her pal Serena Williams to victory.

Meghan, 37, took a break from looking after Archie to watch Williams beat Kaja Juvan on Court One - alongside two friends from her days at Northwestern University in the U.S, sparking speculation they could be her son's godparents.

In only her third public appearance since giving birth, the Duchess was joined by Lindsay Roth, who was expected to be her maid of honour until she decided against having one, and Genevieve Hillis, who co-hosted Meghan's baby shower with Williams.

It was an all-American outing for the Duchess as she and her two US friends cheered on Serena on Independence Day.
