PRINCESS Lilibet turns three today and is likely to be celebrating in California surrounded by family and A-listers.

The Sun spoke exclusively to royal commentator Ingrid Seward about how Prince Harry and Meghan Markle could be celebrating their youngest child’s birthday.

Ingrid shared: “I think she [Lilibet] probably does lead quite an extravagant life because they live in one of the most expensive areas of California, they’re surrounded by movie stars and celebrities and people that have a lot of money and can afford to live an extravagant lifestyle.

“I’m not saying that they would be ostentatious, but I think it would be quietly very extravagant.”

Despite Lilibet’s privileged social circle, royal expert Tom Quinn that the Sussexes prefer a more down-to-earth lifestyle for their kids.

He previously told the Mirror: “Meghan loves homemade gifts and dislikes extravagant expensive presents”.

The Duke and Duchess of Sussex kicked off their daughter’s pre-birthday celebrations on Sunday by hosting a party at their £12million Montecito home with close friends and family, according to Page Six.

But they could celebrate out the house too.

The royal expert shared: “I think they probably would arrange a party outside of their house, and they probably get a whole group of kids and take them somewhere so it’s a bit different.
