Despite palace fears, Meghan Markle has only ‘kind words’ for Kate Middleton in Oprah interview

Buckingham Palace is terrified that Meghan Markle will say nasty things about Kate Middleton on Sunday’s interview with Oprah Winfrey — but sources assure The Post that the duchess offers only “kind words” for her sister-in-law in the otherwise bombshell sit-down.

One scared source even described the interview as equivalent to a "nuclear option" for Markle, the Sun reported. But a source with knowledge of the Oprah interview, set to air Sunday, tells The Post that Buckingham Palace has nothing to worry about in that regard.
