Duchesses’ day out! On Monday, March 11, Kate Middleton and Meghan Markle reunited with their husbands, Prince William and Prince Harry, respectively, to attend the annual Commonwealth Day service at London’s Westminster Abbey.

During the special event — which honors the 53 Commonwealth nations that have Queen Elizabeth as head of state — Kate, 37, pregnant Meghan, also 37, William, 36, and Harry, 34, were also joined by the 92-year-old queen, Prince Charles and Camilla, Duchess of Cornwall.

According to onlookers near the church, Kate and Meghan greeted each other with a kiss on the cheek as they arrived inside Westminster Abbey, the same venue where the Duke and Duchess of Cambridge tied the knot in a lavish royal ceremony back in April 2011. William also allegedly greeted Meg with a kiss on the cheek while brothers Harry and William said hello with a handshake.
