Meghan Markle’s sister disses Prince Harry on his birthday

Samantha Markle has just as many well-wishes for her brother-in-law, Prince Harry, as she does for her half-sister Meghan.

On Saturday, Samantha, 53, tweeted a gif of a hamster chowing down on a birthday cake, writing, “Happy Birthday Harry! As you ‘mack down’ [sic] on your birthday cake, think about the birthday wishes you never extended to your FATHER-IN-LAW.”

Samantha’s diss against the Ginger Prince comes not long after she compared the former “Suits” starlet to Donald Trump.

“People need to stop being so blinded by glare of celebrity status and wealth,” Samantha snapped last week. “Trump said he could shoot someone and not lose votes. The same mentality applies to my sister. People believe anything and still follow in an ant line … She owes my father a lot of love and respect. No one wants to spoil her marriage and marriage is not at issue. What is at issue is the kind treatment of our dad.”

She added, “I am not candy coating anything anymore! The DUCHASS should be humane to our father who has given her everything … and this media crap can stop! He was the one who was always there for her. Fake waves and smiles can stop. The duchASS can bow to the daddy. He only talk [sic] to the media because she was ignoring him for a long time and being snobby,” she added. “He has the right to speak and if she doesn’t like it it’s just too f–king bad. She needs to wake up and be a kind person.”

Samantha and Meghan’s father, Thomas Markle, has been estranged from the Duchess of Sussex since just before the royal wedding in May, when he was busted for allegedly staging paparazzi photos at Samantha’s suggestion.

He backed out of walking Meghan down the aisle after the media firestorm that ensued, claiming he’d suffered a heart attack — which Samantha blamed on Meghan and the royals.

Meghan has not spoken to Thomas since before the wedding, and Thomas claimed that Meghan requested he stop speaking to Samantha.
