Royal biographer Andrew Morton is predicting that Meghan Markle will get pregnant ASAP.
He said: "Meghan will be pregnant before she can spell Torquay".
The writer – who knew Princess Diana – got to know The Suits actress after doing research for a new book on her.
And he believes the new Duchess Of Sussex is planning a family already.
"I think that even before Meghan has learned how to spell Leicester and Torquay she'll be starting a family," he joked.
"She's not really going to be available for working for the Royal Family on a full-time basis until she's 40, I'm sure."
RadarOnline.com had reported that Meghan put a two baby limit ultimatum to her new husband when they discussed starting a family.
The famous biographer, 65, who was rushed to hospital last week after suffering a mini stroke believes Prince Harry, 33, is also keen to start a family after playing uncle to his brother's three children.
Mr Morton told a British newspaper on Sunday that the royal couple will not waste any time starting a family because they're both from 'broken homes'.
Last week the writer and journalist suffered a mini stroke while he was giving a speech in central London, however, he is now recovering at home.
