Mira Sorvino is recalling her “three-day odyssey through the underworld” in the ’90s with Charlie Sheen — including his drug-fueled marriage proposal.

While promoting her Broadway debut in an exclusive interview with Page Six, Sorvino recalled the actor “asking [her] to marry [him] in the car.”

She remembered, “When I said, ‘Not like this,’ because he was high on crack, he said, ‘OK, can I light up then?’ He had a crack pipe in the car, and I was like, ‘No.’”

The Oscar winner also described begging the “Two and a Half Men” alum to get help and following Sheen around as he “disappear[ed] into rooms with people for two hours at a time.”

Sorvino, 58, and Sheen, 60, were longtime pals who had nursed crushes on each other over the years.

The actress’ recollection sharply differs from what Sheen offered up in his memoir, “The Book of Sheen,” published earlier this month.

The “Platoon” star wrote that while on the lam from the police in 1998, he visited guitarist Slash’s home and randomly ran into Sorvino there.

Sheen claimed that Slash, also 60, pleaded with the troubled actor to enter rehab, which Sorvino took one step further.

“Listen to me, you crazy, beautiful man,” he alleged Sorvino said after pulling him aside. “I understand why you don’t wanna go, but you are out of options. … Look at me, Charlie, look at me. I will sleep with you — if you just promise to get yourself to court this morning.”

Sorvino, who has yet to read the book, laughs when she hears the tale.

“I don’t think it actually went down like that. I would beg to differ,” she tells us, before adding that she was incredibly fond of the Emmy nominee.

“He was very beloved to me,” Sorvino, who set the record straight that she did not say she would sleep with Sheen, explains. “We had worked together before. Our fathers were dear friends.”

Sheen’s publicist did not reply for comment.

Meanwhile, the “Romy and Michele’s High School Reunion” star is busy these days starring as Roxie Hart in “Chicago.”

“It’s been so wonderful. It’s very heady, it’s very intense,” she gushes of her Broadway experience. “I love it, I’m so happy. … I love playing Roxie. She’s an amazing character.”

Sorvino teases her version of Roxie being “apparently very different from anybody else’s” as she “bring[s] something new to a venerated show of 30 years.”

She explains, “I see her more, in a way, like a child. … I play her a little bit more innocent and vulnerable than I think [the character] has been played, and I’m enjoying her this way.”

She acknowledges that the intense schedule, including five shows a weekend, means that “sometimes [her] legs feel like jelly just the day before any show.”

Sorvino is also showcasing her vocal talents in the Fox celebrity version of “Name That Tune” on Monday, playing for End Human Trafficking, an organization dear to her heart that she learned about after shooting a mini-series about human trafficking.

“My life changed because I talked to these women who had been trafficked in the United States and had everything taken from them,” the “Summer of Sam” star tells us, “and I could not look away.”
