Clapping back? Friends of Prince Harry and Meghan Markle think Buckingham Palace’s investigation into bullying claims was a calculated move, a source tells Us Weekly exclusively.“The assumption from friends close to Meghan and Harry is that the palace has released this statement to strike back at Harry and Meghan for doing the [tell-all] interview,” the insider adds. “The palace knows that they will not be cast in the best light by Harry and Meghan on Sunday and doesn’t want Harry and Meghan coming off as victims.”Harry, 36, and the Suits alum, 39, will go into detail about their royal exit, family ties and more during a sit-down interview on CBS on Sunday, March 7.
