The male model accused of raping a woman in a Hell’s Kitchen apartment was full of apologies moments after the alleged attack — but only because he’d climbed into bed with the wrong roommate.

“He went into my room, thinking it was me!” the alleged victim’s roommate told The Post Wednesday, describing overhearing the ruckus in the bedroom next to hers after a boozy night out with friends.

“I heard her say, ‘Get off me! Get off me!’ and then he said, ‘I’m sorry! I thought you were [your roommate].”

The ear-witness account adds new detail to the alleged attack by male mannequin Henry Romero, 30, on a young woman in March.

Romero had spent the night drinking with both women and a few male friends, the one roomie told The Post, which is withholding both women’s identities.

The woman who spoke to The Post said she was Romero’s date that night, and had even told Romero that he could sleep on her living room floor overnight to avoid the trip back to Astoria.

But she left the gathering early because Romero began acting creepy as they partied at a gay bar in Midtown, she said.

“He said, ‘I want you to dance for me — that’s why I brought you here,’” the roommate recalled to The Post. “The way he said it was just weird.”

Disturbed, and wanting to get something to eat, she left the bar. Once she returned home, Romero was indeed sprawled on the floor, sleeping.

Meanwhile, her housemate, who was a temporary visitor from another country, for some reason had switched beds with her, she said.

The woman who spoke to The Post said she fell asleep in the other woman’s empty bed — only to awake at 6 a.m.

As Romero apologized, claiming he’d mistaken one of the women for the other, the alleged victim’s voice rose in protest: “What do you mean! She’s blond and I have black hair!”

Romero remains free on $3,000 bail on felony rape charges. He’s due back in court on Aug. 1.

His lawyer, Phillip Hamilton, told The Post, “Henry Romero is not guilty of rape. This was a consensual encounter. The truth of what actually happened is being maliciously twisted in order to portray Mr. Romero in a negative light. I am highly confident that when all is said and done, this matter will be ultimately resolved in Mr. Romero’s favor.
