"Meghan's totally uninterested in how royal births are supposed to be," adds the source who says she won't give birth at St Mary's where Princess Diana and Duchess Kate had their children.
"So she and Harry have Frimley Park hospital which is near their house at Frogmore Cottage on high alert but are determined to bring their baby into the world in the most zen way possible."
As for names, according to the publication the couple are hoping to name their child Diana which is 'infuriating' Harry's brother William.
"He feels like his brother and sister in law would only name the baby Diana for its publicity value."
In terms of gifts Meghan is hoping their child will be spoiled with gifts from dignitaries around the world.
"She's hoping for a white-gold rattle studded with precious gems, just like Princess Charlotte got from the President of Mexico," adds the source.
