Meghan Markle, Prince Harry celebrate Lilibet as Disney Princess

Meghan Markle and Prince Harry's daughter Princess Lilibet, who turned four on June 6, celebrated her big day at Disneyland, reminding fans she's still a princess.

The Duchess of Sussex gave a peek into the family’s fun-filled outing to the California theme park in a new Instagram video, captioning: "It's a Good Day".

She previously thanked Thank Disneyland for giving her family two days of pure joy.

The sweet reel showed the Duke exploring the park with their two kids, Prince Archie, 6, and Princess Lilibet, and one photo in particular had fans zooming in.

At the center of the birthday festivities was a whimsical, tiered cake topped with none other than Ariel from The Little Mermaid.

The Duke and Duchess of Sussex appeared to use Lilibet's birthday cake to send message to the royal family.

The cake also seemed to nod to Lilibet’s own red locks and her love for the classic Disney mermaid. It was adorned with pastel blue frosting and topped with a figure of Princess Ariel, the red-haired Disney character.

The Duchess of Sussex, 43, documented the family celebration on Instagram last week, sharing glimpses of their two-day visit to the California theme park.
