King Charles III is celebrating his 76th birthday.
The Post hears that the royals are expected to mark Charles’ birthday with an intimate celebration this weekend at Highgrove House — the king and queen’s private residence.
“It won’t be a big affair,” a palace source tells The Post exclusively. “A normal dinner that will include a birthday cake.”
Indeed, the cancer-stricken king’s former personal butler has told The Post that “weekends are downtime for the royals.”
Grant Harrold — who worked for Charles for seven years when he was the Prince of Wales — said the royal “usually keeps his birthday quite low-key if they’re not milestones.”
“When I was there, I typically saw phone calls from the family, messages from the public, a selection of birthday cards that are put in front of him so he can see them,” Harrold added.
