And now the Queen is "worried that Meghan will keep the baby trapped at Frogmore, hidden away from the royal family and the rest of the world," adds the insider.
"Meghan seemingly would rather spend time with her new A-list neighbours like the Clooneys and the Beckhams, than Harry's relatives.
"The Queen has been complaining that you can take the girl out of Hollywood but you can't take Hollywood out of the girl."
The publication further alleges that Kate is on her mother-in-law's side, especially since she and William have raised their children with such a normal upbringing.
"Now that there's a baby in the picture, Meghan's diva antics are getting more out of control. Kate's appalled by her ridiculous demands, rolling her eyes when she heard Meghan is already asking palace chefs to create a special plant based menu for her child," they add.
