Meghan Markle celebrates Princess Lilibet’s 4th birthday with delivery room photo

“Four years ago today she came into our lives — and each day is brighter and better because of it,” Markle continued. “Thanks to all of those sending love and celebrating her special day!”

The Duchess of Sussex, 43, and her husband, Prince Harry, welcomed their baby girl in June 2021.

Her first name, notably, was chosen to pay homage to her great-grandmother Queen Elizabeth II as Lilibet was the late monarch’s childhood nickname.

Lilibet’s middle moniker is Diana, honoring Harry’s mother, who died in 1997 when he was 12.

Harry’s daughter was born two years after her big brother Prince Archie’s May 2019 arrival.

Harry and Markle’s eldest child celebrated his 6th birthday last month.

“Our son. Our sun,” the “Suits” alum wrote via Instagram in May. “Happy 6th birthday to Archie! Thank you for all of the love, prayers, and warm wishes for our sweet boy.”

She concluded, “He’s six! Where did the time go? And for all of you who came to celebrate with us at his party last weekend, thank you for making his birthday so incredibly special.”

On her “Confessions of a Female Founder” podcast Tuesday, Markle marveled over her son’s age.

“Where did the time go?” she asked listeners. “I remember carrying him out there. … You look up and everything is in constant fluid motion.”

While Markle did not divulge any details about his birthday bash, the former actress said Archie’s celebration with his pals took place the day before she recorded the episode.

The “Deal or No Deal” alum and Harry have lived with their little ones in a $14 million Montecito, Calif., mansion since 2020.

The couple tied the knot in May 2018, with Markle gushing last month about the “lifetime of stories” they have created in their seven years of marriage.
