Meghan Markle will undoubtedly feel “celebrated” as she rings in her 43rd birthday Sunday.

The Duchess of Sussex will likely mark the occasion with a low-key soiree surrounded by her nearest and dearest — which no longer includes the Windsor clan.

But according to former royal butler Grant Harrold, the “Suits” alum will feel loved alongside her husband and her family, as well as some of her best friends.

Harrold, who worked as King Charles’ butler for seven years, said Prince Harry is believed to be throwing an at-home cookout for his wife on her special day.

“He is a gentleman and a good cook,” Harrold exclusively told The Post. “He is quite old-fashioned like that.”

“They may have a party, they do enjoy summer BBQs outdoors so they might invite friends round for a dinner or a bbq,” he said, adding that the duke “will make sure that Meghan is celebrated.”

As for the other members of the Firm, things are a little more complicated.

Tensions had reached an all-time high after the Sussexes stepped down as senior working members of the royal family in 2020 and moved to the US.

And despite the fact that there’s virtually no communication between the Sussex and Windsor clan, Harrold believes that the mom of two will still receive a birthday message from Prince William and Kate Middleton.

“I have no doubt of that,” he said. “Whether it be electronically, a phone call or a birthday card is hard to say with the ongoing rift.”

“I also think the King and Queen will send their birthday wishes, they will rise above everything that has happened because at the end of the day, they are still family,” the former royal staffer added.

“I don’t think that will change certainly despite everything that’s happened.”

What’s more, Harrold says it’s not too far fetched for Markle to expect a special delivery from the palace.

“They may send a gift as well, but given everything that has happened, there might not be,” he adds. “If they were all still getting on I can imagine it would be a piece of jewelry or something from the royal collection, possibly a hand-me-down from the late Queen.”

“They say blood is thicker than water so I think all the family will send their wishes and possibly a gift,” he added.

As for public messages on social media, the former royal staffer says that Markle shouldn’t hold her breath.

“I doubt there will be any public wishes made, they used to post on social media but that hasn’t happened in the past few years and I doubt that will change,” he said on behalf of Slingo.

Indeed, the Firm was silent on the “Suits” alum’s 42nd birthday last year.

It was a stark contrast to the previous year, when the royals, including the Prince and Princess of Wales, as well as the King and Queen, all publicly shared birthday messages for Markle’s 41st birthday on social media.

For a while, Charles was the only senior member of the royal family who maintained contact with the Sussexes.

However, it’s recently become known that the monarch, 75, no longer takes his estranged son’s calls — meaning there is zero communication between the two camps.
