Writing in his new autobiography Then It Fell Apart, the “Porcelain” singer made claims he dated Portman for a short period.
However, in a recent interview in this month’s Harper’s Bazaar, Portman denied ever having been romantically involved with him.
Now, the musician has shared a photograph on his Instagram account of himself with Portman, reiterating in the caption that he and the Black Swan star briefly dated in 1999.
“I can’t figure out why she would actively misrepresent the truth about our (albeit brief) involvement,” Moby stated in the Instagram caption.
“The story as laid out in my book Then It Fell Apart is accurate, with lots of corroborating photo evidence.”
The singer added that he understands Portman’s “possible regret” in dating him, saying: “I would probably regret dating me, too.”
In Moby’s memoir, the musician claims that when Portman was 20 years old, she once “flirted” with him in his dressing room after one of his shows.
The singer states that he “tried to be Natalie’s boyfriend” for a few weeks, although their relationship didn’t develop any further.

In Portman’s response to his claims, she explained that her recollection of the events is of “a much older man being creepy with me when I just had graduated high school”.
“He said I was 20. I definitely wasn’t. I was a teenager. I had just turned 18. There was no fact checking from him or his publisher – it almost feels deliberate,” the Oscar-winner told Harper’s Bazaar.
She added: “That he used this story to sell his book was very disturbing to me.”
In the book, Moby also claims he briefly dated singer Lana Del Rey in 2006, before she became famous.
“We’d kissed at the bar at 4am, just as the place was closing, and I’d asked her to come home with me,” he writes in the autobiography.
“She’d smiled and said no, she wouldn’t go home with me after just meeting me, but she would happily go on a date if I called her and asked her out.”
Del Rey briefly became a backing singer for Moby’s band The Little Death, before leaving to pursue her solo career.
The Independent has contacted Moby, Natalie Portman and Lana Del Rey’s representatives for comment.
