They include tennis star Serena Williams, actor George Clooney and human rights lawyer Amal Clooney, Canadian stylist Jessica Mulroney, actress Priyanka Chopra, talk show host Oprah Winfrey and of course, the cast of Suits.
While some commentators have said Meghan needs to be careful not to blur the lines between royal and celebrity, PR expert Nick Ede thinks there are a lot of positives to Meghan having high profile friends.
He tells Yahoo UK’s ‘The Royal Box:’ “She’s [Meghan] fantastic as a public speaker, she knows exactly how to talk to every single person.
“She’s also got a really great way of negotiating different things in her life and different events etc.
“I think being a Hollywood star is a fantastic thing, to have that as part of the Royal Family because they are celebrities.
“In the UK we see them as our Royal Family but around the world they’re ambassadors and that’s really what a celebrity is.”
Royal author Phil Dampier says Harry and Meghan are now seen as a global celebrity couple.
“Some people probably don’t even think of them as royal, they just think of them as a glamorous couple, particularly younger people.
“Sometimes I think Meghan is possibly surrounding herself with Hollywood PRs or Hollywood agents and it is slightly different in the Royal Family, so that could cause a problem in the future, but out there in public, they don’t seem to mind.”
But Dampier also added that it could bring “new fans to their causes.”
