Girls' Day Out! Kate Middleton Hangs With Queen Elizabeth and Camilla

Duchess of Cambridge spends some quality time with the in-laws during an event in the Piccadilly area of London

Talk about your royal star sightings!

While gazing upon Kate Middleton alone is certainly more than enough, folks across the pond got quite an eyeful on Thursday when the Duchess of Cambridge was spotted hanging out with grandmother-in-law Queen Elizabeth and stepmother-in-law Duchess Camilla.

So what brought these London ladies together?

The trio hit up the famed food store Fortnum & Mason to help celebrate the refurbishment of the Piccadilly neighborhood.

While there, the gals were not only given a tour of the place—notably the chocolate counter—but they sat down for a little tea party as well. Later, Kate & Co. stepped outside for a plaque unveiling as part of the day's commemoration.

The gathering was just one of several royal events scheduled to take place in the near future as part of the Diamond Jubilee, marking the queen's 60-year (and counting) reign!
