Lori Mattix was part of the baby groupies of the 70s, underaged women that were sexually exploited by rockstars twice their age. She had built up somewhat of a reputation among other predatory men with whom she had sex with, like Jimmy Page and Mick Jagger. At the time, well before the #MeToo movement, being a rockstar had entitled you to all sorts of benefits, like fame, fortune, and statutory rape.
Lori and David Bowie met at a club in 1973, and Bowie was immediately entranced by her, leading to the two eventually hooking up in his suite, even though Bowie was in his mid-20s and she was 14 at the time.
Lori herself talked about this in a 2015 interview with Thrillist, going into extensive detail about the encounter and how he "de-virginized" her, which is about as gross and creepy as it sounds. The #metoo movement recently revived discussion about the baby groupie scene, along with Lori's many encounters with older celebrities, and how a lot of sexual abuse goes under the radar for men with enormous influence. Though this particular encounter hasn't actually been talked about a lot whenever David Bowie's legacy is brought up, which kind of goes to show you the lengths society will go to protect men of status.
