Kate Middleton and Meghan Markle, the Cutest Sisters-in-Law EVER, Curtsy For the Queen

The royal sisters-in-law who curtsy together stay together! Kate Middleton and Meghan Markle joined the rest of the royal family at Buckingham Palace for the annual Trooping the Colour on June 9 and took the opportunity to show their respect for Queen Elizabeth II and celebrate her official birthday. Meghan and Kate talked and laughed together from the palace's balcony, looking like two very happy new sisters-in-law, indeed!

Kate, now seasoned in Trooping the Colour traditions, led the pack in honoring the monarch with the first curtsy. After some speculation that Meghan forgot to curtsy to the monarch on her wedding day, she made her own charming tribute clear on Saturday, followed by a swift head bow from Prince Harry.
