Prince Harry and Meghan Markle were the keynote speakers at an exclusive JPMorgan event — in their first public appearance since leaving the royal family.

The Duke and Duchess of Sussex turned up at the swanky 1 Hotel in Miami’s South Beach on Thursday night, The Post has been told.

A source revealed: “It was all very hush-hush, with a lot of security. Meghan and Harry headlined the event as the keynote speakers.”

The event is believed to be the JPMorgan AIS (Alternative Investment Summit), held annually in Miami and attended by billionaires and high rollers like Bill Gates and Alex Rodriguez.

Miami Beach is a far cry from the cold environs of the Sussexes’ $14 million Canadian bolthole, where People magazine this week reported they have been lying low with baby Archie, practicing yoga and walking their dogs.

It’s as yet unknown how much they were paid for the event, though the pair have said they plan to make themselves financially independent, so they will be paid for gigs like this.

As we have reported, they are searching for a new CEO of their Sussex Royal charitable foundation, and hunting for a place to spend the summer in LA, close to Meghan’s mom, Doria Ragland.

Energy entrepreneur Michael Hess, the husband of Meghan’s best friend, Misha Nonoo, has already offered them a place to stay in the gated Malibu Colony, dubbed “Billionaire’s Beach.”

A spokeswoman for the Sussexes declined to comment, saying: “We do not comment on their private schedule.”

JPMorgan declined to comment.
