The Prime Minister of Antigua had the 32-year-old cringing when he decided to comment on Harry's personal life, in front of hundreds of guests at a reception held in his honour.
“I understand that there may be a new addition to the royal family very soon," Gaston Browne jovially addressed the Prince, who looked less than impressed.

"I am told that there may be a princess and I just want to say that should you make the decision to honeymoon - then Antigua and Barbuda want to welcome you."
"We have been voted consistently as the best honeymoon destination in the Caribbean - and one of the best in the world - so there will be nowhere in the world as special to spend your honeymoon, when that day arrives."
Onlookers at the official engagement noticed that the Prince was "clearly embarrassed" by the comments.
"He went bright red," one guest noted to Us Weekly, adding he quickly looked down at his feet.
The island's PM, 49, also joked around with the good-natured royal as they met with six of the island’s beauty queens.
"You are the coolest member of the royal family and one of the most successful ones."
“Whatever is done here, stays here. So do not worry,” the politician remarked.
Despite Harry stipulating his relationship was off-limits during his royal tour, Gaston still decided to share his views on the exciting new development.
"I believe Meghan is a very beautiful looking girl, they make a very good looking couple,” he said.
Adding, "I hear they are speculating that they will now get married. I hope that Harry and Meghan come here for some quiet time very soon.”
