THE TELL-ALL THAT'S ROCKING THE PALACE!

Meghan and Harry have shocked the royals with their plan to open up to chat-show queen Oprah

Buckingham Palace faces an anxious wait for March 7, when the rogue Duke and Duchess of Sussex will sit down for a stunning 90-minute prime-time interview with their friend, Oprah Winfrey.

The CBS network promises it will be a no-holds-barred chat with Meghan about her life as a royal and the “pressures of public life” – and that Harry will join later to discuss what’s next for his family.

Palace aides have confirmed the appearance was not sanctioned by nor even discussed with the royals, with one source coldly responding, “They left. They’re free to do whatever they want.”

But insiders tell Woman’s Day that behind closed doors, everyone from the Queen, 94, to the press office is “in a mild panic” over the blindsiding interview. And Oprah’s best friend, Gayle King, has done little to ease the royals’ concerns, revealing, “I’m told nothing is off-limits... she can ask anything she wants.”
