Prince Harry and Meghan Markle are set to host a heartwarming celebration for their daughter, Princess Lilibet Diana's upcoming birthday, amidst maintaining a low profile following their distressing encounter with paparazzi in New York City on May 16.

The second birthday of Lilibet Diana on June 4th is undoubtedly a joyous occasion for the Duke and Duchess of Sussex. A cozy, private gathering at their palatial Montecito residence in Santa Barbara, California, is being planned by the duchess, renowned for her enthusiasm in organizing festive celebrations, as demonstrated in their Netflix documentary "Harry & Meghan".

As shown in past celebrations, birthdays hold a significant place in the Sussex family's hearts. Notably, Prince Harry made sure to swiftly return to California from King Charles III's coronation on May 6th, which coincided with their son Archie's fourth birthday, to be a part of the celebrations.

It's expected that Princess Lilibet Diana's second birthday will be marked with a distinct flavor than her first, celebrated in the U.K. amidst Queen Elizabeth II's Platinum Jubilee festivities. The family had enjoyed a serene picnic at Frogmore Cottage during their visit, with an intimate gathering and an endearing rendition of "Happy Birthday" for the young princess.

A heartwarming memory from Lilibet's first birthday was a candid snapshot taken by photographer Misan Harriman. Also, Claire Ptak, the pastry chef behind the Sussex's wedding cake, baked a delightful lemon and elderflower cake with strawberry buttercream frosting, replicating the wedding cake's flavor.

Notably absent from the party were Prince William and Kate Middleton, along with their children, due to prior commitments. King Charles and Queen Camilla were also unable to attend.

In line with their tradition, the Sussex family is launching a KABOOM fundraiser through the Archewell Foundation, to commemorate their children's birthdays and aid the Uvalde, Texas community's healing process. The announcement reads, "Together we can make a difference to help build playgrounds that end playspace inequity!" The campaign has impressively raised $88,479, far surpassing the initial goal of $20,000.

Post Princess Lilibet Diana's birthday celebrations, Prince Harry is slated to return to the U.K. for a legal hearing. As per reports by Hello! magazine, he will provide testimony in his privacy lawsuit against Mirror Group Newspapers (MGN) over allegations of unlawful information procurement.
