Meghan Markle’s brother unexpectedly releases biza...

Meghan Markle’s estranged half-brother has been accused of “betrayal” after sharing a savage new YouTube video in which he dresses up as the duchess and accuses her of faking her pregnancies.

Thomas Markle Jr., 57, donned a wig and a tiara in the 87-minute video posted to the platform on Wednesday, while stuffing a pillow up his shirt to imitate a pregnant woman.

“My name’s Me-again Swamp-donkey Crotch,” Thomas declares during the bizarre impersonation. “I was just showing off the new bump I bought used on eBay out of Montecito.”

Royal commentator Jennie Bond slammed the video on Sunday, telling the Daily Mail: “To have your own flesh and blood lead the assault must feel like the ultimate betrayal for Meghan.”

She further described the footage as “grotesque.”

She further described the footage as “grotesque.”

“If you don’t like it, don’t watch, right? I’m gonna be riding those coattails, baby,” he says in the clip. “Oh, yeah, if it wasn’t for Meghan Markle I don’t know what I’d be doing.”Thomas has reportedly not spoken to his half-sister in more than a decade, but seemingly has no qualms about milking his connection to the royal.

“If you don’t like it, don’t watch, right? I’m gonna be riding those coattails, baby,” he shamelessly says in the clip. “Oh, yeah, if it wasn’t for Meghan Markle I don’t know what I’d be doing.”

According to The Mirror, Thomas plans to bring out his a range of merchandise, including lines of glasses, mugs and T-shirts.

Thomas, who works as a window fitter and lives in Grants Pass, Ore., is one of Meghan’s two half-siblings.

The duchess’ other half-sibling is Samantha Markle, 59, who has also cashed in on her connection to the royal.

Samantha, who is similarly estranged from Meghan, has brutally described the former “Suits” star as having “narcissistic personality disorder.”

Last month, Samantha lost a defamation suit she brought against her estranged sister, with a judge saying Samantha had “failed to identify any statements that could support a claim for defamation or defamation-by-implication” made by Meghan.

The budding lifestyle maven — who is soon set to launch her brand American Riviera Orchard — looked happy and relaxed as she joined Prince Harry in Florida earlier this week, where he is shooting a new Netflix series about polo.
