Royals A Kiss for Granny! See Kate Middleton's Perfect Curtsy to Queen Elizabeth at Chelsea Garden Show With one foot behind the other, Kate quickly bent her knees and smiled at the Queen as the trio continued their conversation By Erin Hill Erin Hill Twitter Senior News Editor, PEOPLE People Editorial Guidelines Published on May 20, 2019 02:37 PM Share Tweet Pin Email Kate Middleton showed off her perfect curtsy to Queen Elizabeth once again! The royal mom of three returned to the Chelsea Flower Show on Monday evening after spending the day showing kids around her new garden exhibit. And after showing her project off to her own kids — Prince George, Princess Charlotte and Prince Louis — Kate was ready to give her grandmother-in-law, Queen Elizabeth, the grand tour. After Prince William greeted his grandmother with a kiss on both cheeks, Kate followed suit by placing a hand on the Queen’s arm and greeting her with the same style kiss. In a video from The Sun‘s Emily Andrews, Kate is seen following her greeting with a quick but perfect curtsy. With one foot behind the other, Kate quickly bent her knees and smiled at the Queen as the trio continued their conversation. Kate expertly trained her 4-year-old daughter, Princess Charlotte, who debuted her own adorable curtsy during the royal family’s tour in Germany and Poland in 2017. Watch Princess Charlotte Boss Prince George Around Mom Kate Middleton’s Garden: ‘Quicker George!’ Myka Meier, founder and director of Beaumont Etiquette, previously told PEOPLE that a curtsy should be subtle and that the deeper and longer you pause shows more respect and formality. To curtsy, Meier instructs placing one leg behind the other (whichever one is more comfortable for you) and bowing your head slightly while bending your knees.

Kate teamed up with two designers, Andrée Davies, 55, and Adam White, 45, for the “Back to Nature”-themed garden, which is meant to be a fun place for families to experience a natural environment together and enjoy the relaxing benefits of nature.

I really hope that this woodland that we have created really inspires families, kids and communities to get outside, enjoy nature and the outdoors, and spend quality time together.” Prince George and Princess Charlotte.

The family sat in a den that they had all helped source wood to build, while George and Charlotte took off their shoes and dipped their feet in the stream beneath a waterfall, and little Louis, 12 months, was seen walking and brandishing a stick.
