Singer and actress Jessica Simpson recently revealed details of a secret past romance she had with a “massive movie star” in an interview with PEOPLE.

Simpson, 40, said the romance was a “short-lived” affair, but it was “intense” and that she “took the pillowcase he slept on.” She also said that the movie star had a girlfriend at the time.

The star, who has been married to former NFL player Eric Johnson since 2014, also said she felt “like a call girl” during the relationship.

Simpson, who is promoting her new memoir Open Book, said that the star was “very charming” and that she had “never been in a situation like that before.”

The romance was kept under wraps for many years, but Simpson said that she felt it was important to share her story.

“I thought I would never share it,” Simpson said. “But I’m not ashamed of it anymore. I’m in a different place now and I can talk about it without feeling embarrassed.”

Simpson’s memoir is set to be released on February 4, 2020.
