Lilibet is pictured in new photos taken on Saturday at a party in Windsor to mark her first birthday.
She turned one on Saturday and the images were taken at her birthday party at their Windsor home, Frogmore Cottage.
The pictures are by Nigerian-born British photographer Misan Harriman.
"It was such a privilege to celebrate the 1st birthday of Lillibet with my family and hers! Joy and face painting all around," said Harriman on Instagram.
He tweeted a black and white photo of Meghan holding Lilibet, alongside his own wife and children.
Vogue said close family and friends were at the party, which it described as an "intimate and casual backyard picnic".
It said guests are understood to have included Harry's cousin Zara Tindall, her husband Mike, and their children.
The last picture of Lilibet released was for the couple's Christmas card last year.
Her birthday cake was reportedly made by Claire Ptak, from East London's Violet Bakery, who also made the Sussexes' wedding cake.
Harry and Meghan were in the UK for the Queen's jubilee celebrations.
They were at the thanksgiving service at St Paul's on Friday but were kept separate from the Cambridges and the Prince of Wales.
Meghan was also seen giving a playful shush to Mia and Lena Tindall as she watched Trooping The Colour.
It's believed they have now flown back to their home in Montecito, California.
