Prince Harry and Meghan have been warned not to let the actress’s half-sister anywhere near the royal wedding in May.
For the first time, Samantha Markle’s ex-husband lifts the lid on their nightmare marriage, revealing he wanted a divorce just a WEEK after they tied the knot.
And he claims the “fame hungry” ex-model – who has branded Meghan “Princess Pushy” – was never as close to Harry’s bride-to-be as she said she was.
Scott Rasmussen, 59, said: “Samantha’s the pushy one. She made our marriage a living hell.
"I believe she resented Meghan because she had the life Samantha always wanted and she was jealous.
“Harry and Meghan need to know the truth about her. She’s the last person who should be at Windsor Castle.”
There are rumours that if Samantha, 52, doesn’t get an invite she will comment on the ceremony for an American TV network.
“In my opinion, if she sets foot in the UK they should send her straight to the Tower of London,” said Scott.
The movie firearms expert, who has been working with Aussie star Margot Robbie on a new film, says he has been sickened by his ex-wife’s interviews telling how she helped give Meghan a “magical” and “fun” childhood.
“Samantha making out they were close is bulls***,” said the ex-Marine.
Scott and Samantha met in 1997 in New Mexico, when they were both trying to make it as actors.
He fell head over heels and they married a year later.
He even paid for her to have her name changed from Yvonne as a wedding present.
“The star’s name in TV show Bewitched was Samantha. She liked that,” he said.
But the spell was soon broken.
Scott said: “A week after we married, my best friend invited us for dinner.
"When it was time to go, she was in the bath fully dressed. She had the oddest look, and said, ‘Tell them you’re sick.
"I want nothing to do with your goddamn friends’. I was blown away. From that day I wanted a divorce. I even saw an attorney.”
Scott says he only stuck with her as she was pregnant with daughter Noel.
Meghan, 36, and her dad Tom – who had Samantha during his first marriage – had been unable to make the wedding, but visited the couple in 2000.
He said: “Meghan was a teenager. She was all class and so polite, everything Samantha wanted to be.”
As the Suits star’s acting career blossomed, Samantha’s didn’t.
“She only got bit parts. She tried being a model but it didn’t work out,” said Scott.
“She got bitter.” Scott left Samantha in 2003. He later got custody of Noel, now 19.
Samantha is now writing a book on Meghan, with the working title The Diary of Princess Pushy’s Sister.
Scott said: “She should act with some dignity, keep her mouth shut, and leave everybody else alone.”
Samantha hit back, saying: “He wants to take advantage of my sister’s high profile.
Scott vowed to get revenge when we got divorced. He is saying anything he can right now to disparage me.
“When it came out that I am writing a book and that my sister is marrying royalty, he thought, ‘A-ha, I’m going to get her.’”
