Royal family members send sweet messages to Prince Harry and Meghan Markle's daughter Lilibet on her 1st birthday

• Royal family members are sending Prince Harry and Meghan Markle's daughter birthday wishes.
• Lilibet Diana, born on June 4, 2021, is named after Queen Elizabeth and the late Princess Diana.

As Prince Harry and Meghan Markle celebrate their daughter Lilibet Diana's first birthday on Saturday, royal family members are sending birthday wishes to the youngest member of the Sussex family.

Insider's Samantha Grindell reported last month that Queen Elizabeth II was expected to meet her great-granddaughter for the first time during her Platinum Jubilee celebrations this weekend. A source confirmed with Entertainment Tonight on Friday that the Queen met her namesake after Trooping the Colour on Thursday. The source also told ET that the Queen will see Lilibet again on Saturday.

The official Twitter account of the royal family and the Queen shared "very happy" birthday wishes to Lilibet this weekend.

Hairdresser George Northwood, who styled Meghan's hair at Friday's thanksgiving service, shared photos of the duchess on his Instagram. In the caption, he wrote that it was "so nostalgic and wonderful" to be reunited with Harry, Meghan, and their family, saying "Archie has grown to be the cutest, well mannered little boy and Lilibet is just beautiful."

Lilibet was born on June 4, 2021, in Santa Barbara, California. Her name is a tribute to the Queen's family nickname, which biographer William Shawcross wrote was coined by Queen Elizabeth's grandfather King George V. Lilibet's middle name, Diana, came from her paternal grandmother, the late Princess Diana.

Vanity Fair's Katie Nicholl reported last year that Prince Harry sought the queen's "blessing" to name his daughter after her.

Neither Lilibet nor her older brother Archie has been seen publicly at any Platinum Jubilee celebrations so far. The Guardian reports that the Duke and Duchess of Sussex are expected to celebrate their daughter's birthday at Frogmore Cottage, about a mile from Windsor Castle.

Representatives for the Duke and Duchess of Sussex did not immediately respond to Insider's request for comment.

The royal children have made headlines during Platinum Jubilee events. William and Kate's youngest son, Prince Louis, was photographed screaming on the Buckingham Palace balcony while planes flew overheard during the Trooping the Colour Thursday.
