Moby, who has a history of making rather provocative outbursts, claimed to have dated Natalie Portman when she was 20 and he was 33. He claimed in a memoir published last week, titled Then It All Fell Apart, that they briefly dated after flirting with each other.However, Portman has a very different account of their brief "fling" and presented her perspective in an interview with Harper's Bazzar.“I was surprised to hear that he characterized the very short time that I knew him as dating because my recollection is a much older man being creepy with me when I just had graduated high school,” she told the magazine. “He said I was 20; I definitely wasn’t. I was a teenager. I had just turned 18.” Portman's description of their "relationship' was that she was a fan of his and met him backstage after a show: “We only hung out a handful of times before I realized that this was an older man who was interested in me in a way that felt inappropriate.”However, since the initial claim in his book, there have been more developments.On Wednesday, on Instagram, the 53-year-old singer became more resolute in his initial claims of them having a brief romance, alongside a photo of the pair of them from the period of time in question. “I recently read a gossip piece wherein Natalie Portman said that we’d never dated,” Moby wrote. “This confused me, as we did, in fact, date. And after briefly dating in 1999 we remained friends for years. I like Natalie, and I respect her intelligence and activism. But, to be honest, I can’t figure out why she would actively misrepresent the truth about our (albeit brief) involvement.”The singer continued by saying that the account in his memoir “is accurate, with lots of corroborating photo evidence,” adding that he would certainly understand Portman regretting dating him, “but it doesn’t alter the actual facts of our brief romantic history.”Amy Spiro contributed to this report.
