The former Prince Andrew allegedly had an unsavory pickup line that he would employ on unsuspecting women.

Andrew Lownie, who wrote “Entitled: The Rise and Fall of the House of York,” which is coming out in paperback with new material later this month, spoke to Page Six exclusively on Tuesday about the royal’s stomach-turning attempts at seduction.

“His chat-up line was, ‘What’s it feel like to have the royal c–k against your thigh?'” Lownie claimed. “I mean, just [an] extraordinary sense of entitlement, right?”

And that wasn’t his only come-on.

Lownie claimed that when the former Duke of York was introduced to a female flight attendant on a plane, she put her hand out to shake his, while Andrew “whirls around, basically sticks his groin in her backside and then practices [a] golf swing.”

The author alleged that there are “just lots and lots of stories” of Andrew behaving badly, adding that the former royal has “a strong sense of entitlement” and seemingly enjoyed embarrassing women.

“It’s sort of sexual humiliation,” Lownie claimed, like “pulling down the zips” on women’s dresses at balls and “leaving them embarrassed.”

A rep for Andrew did not immediately respond to Page Six’s request for comment.

Last year, King Charles stripped his brother of all his royal titles amid the ongoing scandal regarding his ties to late pedophile Jeffrey Epstein. He and his ex-wife, Sarah Ferguson, were also tossed from their longtime home, Royal Lodge.

He is now known as Andrew Mountbatten-Windsor.

Mountbatten-Windsor was also accused of raping Virginia Giuffre when she was a minor. Giuffre claimed she was sex-trafficked by Epstein and his sidekick, Ghislaine Maxwell. He vehemently denied the charges but made a multimillion-dollar payment to Giuffre, who died by suicide in April 2025.

Most shockingly, the disgraced royal was arrested in February, on his 66th birthday, on suspicion of misconduct in public office for allegedly forwarding confidential trade documents to Epstein.

If convicted, he could face a maximum sentence of life in prison.
