Bad blood between Meghan, Kate?

Meghan Markle does not seem to be making many friends at Kensington Palace, as RadarOnline.com has learned, she even made Kate Middleton burst into tears before her wedding to Prince Harry.

Kate’s teary breakdown came after Meghan’s “stressful” dress fitting, a royal insider told The

Sun. At the time, the former actress insisted on “the very best,” in preparation for her big day — but the fitting did not go as smoothly as planned.

Meghan’s stress over the matter quickly became too much for the Duchess of Cambridge to handle and staffers allegedly caught her crying in despair.

“Kate had only just given birth to her third child, Prince Louis, and was feeling quite emotional,” said the insider.

As Radar readers know, various sources previously told the publication that Kate, 36, and Meghan, 37, are simply “very different people” who support different causes and want different things — and because of that, they don’t really get along.

Insiders also said that Meghan’s arrival into the royal family caused a bit of a rift between Harry, 34, and brother Prince William, 36, and was part of the reason the parents-to-be decided to find a home outside the palace.

Plus, according to royal correspondent, Richard Palmer, staffers and royal family members believe the former

Suits star to be “difficult and demanding” — though Harry is just too lovestruck to see it.
