The Duke of Duchess of Sussex appeared to have the time of their lives as they carried out their 16-day Royal Tour of Australia, Fiji, Tonga and New Zealand.
"Everyone was so warm and welcoming to them," a source told OK! USA.
"They both really enjoyed themselves."
However, OK! USA claims things are about to get a lot more hectic for the royal pair, who are expecting their first child next year.
"There has been talk that once the tour ends, Harry and Meghan will be making a historic announcement that will rock the palace to its core," an insider dished.
"They'll be revealing that they're leaving the royal life behind."
The insider adds to OK! there are whispers that Harry wants to give up his title.
"His priorities have shifted now that he has a baby on the way," a palace source tells the US publication.
"Meghan and their children come first now. As much as he enjoys royal duties, if getting out of the monarchy is the best thing for his family, that's what he's going to do."
OK! USA's insider adds, "There's buzz that they are planning to relocate to America.
"Meghan grew up in California and thinks it would be the perfect place to raise a family. Harry would do anything for her, so he's agreed."
However, the Duke and Duchess' big move doesn't come without ruffling some feathers.
"Harry knows that his grandmother, Queen Elizabeth, will be the most upset when she finds out."
It's also the public scrutiny that Harry wants to get away from, OK! reports.
"Harry has experienced all the negatives that come with being a part of the Royal Family," adding he'll do "anything to protect his family."
The Royal Family is yet to respond to OK!'s report.
