A German model claims to have been in the same room with Donald Trump during an alleged romp he had with Playboy Playmate Barbara Moore.

She spoke to the Daily Mail about the tryst, which supposedly went down while Trump’s second wife and then-fiancee Marla Maples was pregnant with daughter Tiffany.

“I was just sitting there and they got into a little sexual thing,” recalled model Elke Jeinsen.

“They actually had sex together and I was watching it,” she said, noting how the alleged hookup happened at Trump Tower in the summer of 1993, while she was also posing for Playboy.

“It was like they didn’t even know I was in the room, I didn’t exist,” Jeinsen added. “He was really into Barbara.”

Moore, 49, came forward in April and claimed to have had a six-month affair with Trump while he was with Maples. She said the secret relationship began in March 1993, just three months after she was named Playboy’s Miss December centerfold.

Jeinsen was a centerfold herself, but The Donald didn’t care — he was honing in on Moore.

“We were talking, laughing, drinking, sitting on his bed and then he started to undress Barbara and make out with her,” Jeinsen said. “We were sitting there sexy-dressed and Barbara got slowly sexy undressed. She was beautiful and he was totally into her and he helped undress her. We were Playboy girls, we were used to being sexy and playing.”

The model added, “I was sitting there half undressed, not naked but in lingerie, and then they started kissing and making out. I was not included in the sex, but I was included in the conversation beforehand so it was strange for me.”

It wasn’t the only thing that stuck out to Jeinsen.

“On TV his place was all in gold — there was no gold in this room,” she told the Mail, remembering how Trump whisked her and Moore away into “a normal guest room.”

“I wasn’t impressed,” Jeinsen said. “I expected a little bit more…I expected like a suite with gold and silver. So I was a little disappointed.”

The former playmate admitted that while she was weirded out by the whole experience, she could tell that the feelings Trump and Moore allegedly had for each other were genuine.

“I was not jealous, Barbara was my best friend and I knew they had something,” Jeinsen said. “I knew it’s not just a one time thing, it was real.”
