Former teen “sex slave” Virginia Roberts Giuffre says she finally fled Jeffrey Epstein and Ghislaine Maxwell after three years, when they asked her, at age 19, to bear their surrogate baby.

The latest creepy allegation by Giuffre, who has also accused Epstein of pimping her out to Prince Andrew when she was just 17, was revealed by her attorney, Bradley Edwards, in his new memoir, “Relentless Pursuit.”

“It was the final straw,” Edwards writes in an excerpt published in the Daily Mail.

“She knew she had to escape.”
