Prince Harry and Meghan Markle are giving their fans a glimpse of the backyard picnic they threw for their daughter, Lilibet Diana.

The young royal turned one on Saturday, June 4. The Duke and Duchess of Sussex, who were in the UK for the Queen’s Platinum Jubilee celebrations, held Lilibet’s party at their Frogmore Cottage home in Windsor.

Several royal family members attended, including Mia, Lena, and Lucus – the children of Harry’s cousin Princess Zara and her husband Mike Tindall.

Peter Phillips and Autumn Kelly’s children Savannah and Isla were reportedly also in attendance.

Photographer Misan Harriman, a close friend of the couple, attended the picnic with his wife Camilla Holmstroem and their two children.

Harry and Meghan allowed the photographer to take pictures at the party, which he later shared on his Instagram page.

“It was such a privilege to celebrate the 1st birthday of Lilibet with my family and hers! Joy and face painting all around,” Misan captioned three pictures from the celebrations.

No new pictures of their three-year-old son Archie were shared. But according to Meghan’s hairdresser, George Northwood, he is “the cutest, well mannered little boy”.

Claire Ptak, the baker behind the couple’s wedding cake, reportedly made Lilibet’s first birthday cake.

A spokesperson told Harper’s Bazaar that Harry and Meghan “remain incredibly touched by the countless birthday wishes for their daughter”.

It’s not the first picture the couple has shared of their little girl. They celebrated their first festive season as a family of four by sharing a Christmas card.

The Christmas card featured both Archie and Lilibet. It was taken at their home in California.

Queen Elizabeth met Lilibet for the first time last week.

Harry and Meghan made two appearances at the Queen’s Jubilee celebrations. They watched the Trooping the Colour parade from the Major General’s Office.

They were also pictured at the Service of Thanksgiving event at St Paul’s Cathedral.
