In fact, royal expert Katie Nicholl speculated that if they continue to secure multi-million dollar business ventures, they could soon have a "billion dollar brand." And while that's great news for the Duke and Duchess of Sussex, members of the royal family may suffer the repercussions of their fame and fortune.
"What Harry and Meghan have done over the past 12 months is sow seeds which will spell potential catastrophe to the royal family," royal biographer Duncan Larcombe said of the power couple's success on True Royalty TV’s Royal Beat.
"When 50 million people are watching Harry's chat about organic yoghurt or whatever it is that he wants to promote, and 5,000 people are watching his brother, Prince William, the future King, do a royal engagement, opening a supermarket in Hemel Hempstead or whatever — that is when it becomes a problem," he explained.
Larcombe then threw shade at Harry, 36, and Meghan, 39, who claimed they wanted to step away from their royal duties to live a more private life and give son Archie a normal childhood. Since Megxit, the duo has signed an $150 million deal with Netflix and multi-million dollar Spotify deal as podcast hosts.
"It was the biggest royal sellout in the history of the family," the biographer proclaimed.
The pair's controversial moves are sure to ruffle a few feathers with his older brother, as their relationship is still not back to normal.
"This time last year [Prince William and Prince Harry] weren't talking to one and another," Nicholl explained. "Things are better. There are still things to overcome but I think they all realize that you do have to move on in life."
And while the couple's post-royal set up in the U.S. seems to be working in their favor, the decision on Prince Harry's military titles still hangs in the balance. As OK! previously reported, Queen Elizabeth II is due to decide if she will extend the couple's Megxit deal, which will solidify where her grandson stands.
Harry and Meghan are set to return to England to celebrate Her Majesty's 95th birthday, and Nicholl stated that "the intention is that the four [including Markle and Kate Middleton] of them will be together for the unveiling" of Princess Diana's statue at Kensington Palace.
