The Sun UK reports the newly minted Duchess of Sussex is coaching her husband in speaking and stage presence to give him more "confidence" in front of the public.
Meghan, 37, reportedly hopes to boost the couples "star quality" by imparting some of her Hollywood expertise to the Prince.
A source close to the royal couple told the Sunday Express Harry is undergoing "extensive" training with the former Suits star as his mentor, and the insider says the classes are woring wonders.
"You only have to look at the Duke to see how much more relaxed he is on stage - he used to be nervous and embarrassed."
Meghan is said to have taught Harry to memorise his speeches and work the stage to command more attention from the audience.
But not all royal associates are so pleased with Harry's newfound confidence.
The Sun's former royal editor Duncan Larcombe slammed the Duke's recent address at Wembley Arena for WE Day as "stomach churning hippie talk".
The father-to-be brought heavily pregnant Meghan on stage with him to speak to a crowd of millennials, which Larcombe described as a move that "wouldn't have looked out of place in some kind of fundraising dinner in Hollywood".
