Prince William, Kate Middleton Wish Harry And Meghan's Daughter Lilibet A Happy 1st Birthday

Prince Harry and Meghan Markle's daughter, Lilibet "Lili" Diana, turned 1 Saturday — and the royal family is celebrating the major milestone.

Amid the ongoing festivities of Queen Elizabeth II's Platinum Jubilee, several members of the royal family took to social media to wish Lili a happy birthday, including her uncle Prince William and aunt Kate Middleton.

"Wishing a very happy birthday to Lilibet, turning one today!" the Duke and Duchess of Cambridge tweeted Saturday.

Prince William and Middleton received praise from social media users and royal fans for their thoughtfulness amid rumors that Prince Charles' two sons have yet to reconcile.

"Very gracious of the Cambridges, not surprising though. Happy birthday, Lilibet," one Twitter user commented.

"The most secretive, most hidden baby of all time! But as always, bravo Cambridges for being the bigger people in all of this," another added.

"They've always been the bigger people in all the drama. That simply explains why they're much loved and respected," a third user wrote.

"Pure class. This is why we adore you. Thanks always for your grace, compassion, and kindness. Always above the fray and truly royal," a Cambridge fan tweeted.

In addition to Prince William and Middleton, Queen Elizabeth also shared her birthday wishes for her great-grandchild—who is named in her honor—via her Twitter account, posting: "Wishing Lilibet a very happy 1st birthday!"

Lilibet's grandfather Prince Charles and Camilla, Duchess of Cornwall tweeted: "Wishing Lilibet a very happy 1st birthday today!"

None of the royal family's posts included a photo of Lili. Prince Harry and Markle have shared only one snap of their daughter since welcoming her in June 2021. Lili was featured on their 2021 Holiday card, along with her parents and big brother, Archie, 3, E! News reported.

Prince Harry and Markle have been in England with their two children since Tuesday for Queen Elizabeth II's Platinum Jubilee festivities. The visit marked the first time the toddler met the Queen since her birth.

Prince Harry and Markle have lived in California since 2020 after stepping back from their roles as senior working members of the royal family. They made their exit official in February 2021.

It has been reported that Queen Elizabeth skipped the Epsom Derby in favor of meeting Lilibet and spending time with her on her first birthday, according to Marie Claire.

Prince William and Middleton, however, were scheduled for a royal engagement that day.

The Duke and Duchess of Cambridge were set to visit to Cardiff Castle in Wales to meet the performers and crew members taking part in the Platinum Jubilee Celebration Concert to be held on the castle grounds Saturday afternoon.
