Meghan Markle might be learning all things British, but she's not ready to start driving on the other side of the road just yet.

The royal-to-be joined Prince Harry and the Duke and Duchess of Cambridge at The Queen's Pre Christmas Luncheon at Buckingham Palace.

Talk about a pressure-packed 'brunch with the in-laws'.

Pretty much all the most famous Royal faces were in attendance and, yes, all the men did the driving.

Must be a royal thing ... Queen Elizabeth is 90-something and always in the driver's seat!
