Prince Harry has reportedly warned Meghan Markle following Martha Stewart remarks days after their secret meeting with King Charles.

Martha said she had recently attended a California dinner with Meghan after the Duchess returned from the palace, and suggested she had been gossiping about the trip.

Then Meghan’s camp pushed back, and the dinner’s host contacted the People and called Martha’s account “simply untrue.”

They insisted Meghan said nothing about the European trip beyond “the family had a great time.”

Martha was even described as “confused.”

Following this development, Harry has warned Meghan as he has given his father King Charles and everyone on the King’s staff these assurances that “he and Meghan will both be total vaults and then this comes out – it’s an absolute nightmare.”

As a result of the recent furore, it has been claimed that Duke has now taken a stand – telling his wife that it’s “safest” to avoid Hollywood parties for now.

The insiders have told the publication, “Just to make sure nothing like this happens, because he feels they cannot afford any missteps and clearly nowhere is safe.”

However, Meghan is ‘adamant’ that she absolutely was not sharing anything private, or anything at all for that matter.

But unfortunately that doesn’t really undo the damage that Martha’s comments have done, the sources further claimed.
