'Silent Treatment!' Inside 'Snobby' Camilla's Fiery Feud With Meghan

Move over, Kate Middleton!

Meghan Markle's got a new family member she's feuding with – her mother-in-law!

"The drama with Meghan and Kate is nothing compared to what's going on with Camilla," a source snitched to RadarOnline.com exclusively.

As readers know, the newest member of the royal family has been on the outs with her other in-law – Kate, 37 – even skipping out on her January 9 birthday.

Now Prince Charles' wife, Duchess Camilla Parker Bowles, is giving the Hollywood star the silent treatment.

"Camilla doesn't really talk to Meghan," added the source. "She is snobbiest and least friendly."

"Camilla even told her 'this is real life and you're not an actress playing a role.'"

Despite the insults, the former Suits beauty, 36, is determined to be a happy family.

"Meghan has tried everything to get Camilla to warm up to her and nothing has worked."

"She wants to be close to her, but Camilla isn't allowing it."

Markle, however, has allies inside Kensington Palace. As RadarOnline.com has reported exclusively, Queen Elizabeth never approved of Camilla and the torrid affair she was carrying on with Charles while he was married to Princess Diana. The 91-year-old monarch even referred to her as a "wicked woman."

And Prince Harry, 34, is easing his newlywed wife's mind about Camilla's cold shoulder.

"William and Harry aren't close to Camilla either, so Harry is telling her not to worry about it. He's told Meghan she's the mistress to his father so just forget about it. She's not important to their happiness."

In the meantime, the pregnant Duchess, who's due in the spring, is focusing her energy on being "calm" ahead of the birth of her first child.

The newly-minted Duchess has been working with a doula who has regularly visited her and Harry's homes in both Oxfordshire and at Kensington Palace, according to Us Weekly.

"Meghan is focused on calm and positive energy around the birth — she's a big believer in that."
