Foxe had affairs with David Bowie and James Williamson of The Stooges while working under Tony Defries as a publicist for MainMan, Bowie's management company. She also appeared in the music video for Bowie's 1973 single, "The Jean Genie."
Having grown up idolizing the Rolling Stones, Foxe became closely associated with the New York Dolls, a band often compared to the Stones. In 1977, after years of dating, she married David Johansen, the band's lead singer. It was while Foxe was married to Johansen that she met Aerosmith's lead singer, Steven Tyler.
After less than a year of marriage to Johansen, Foxe left him for Steven Tyler. Foxe and Tyler married and had a daughter, Mia, but the marriage was troubled by drug addiction, extramarital affairs, and physical and emotional abuse. Foxe and Tyler divorced shortly before Aerosmith made a comeback in the late 1980s. She raised Mia in Sunapee, New Hampshire and New York City.
In 1997, Foxe's memoir, Dream On: Livin' on the Edge with Steven Tyler and Aerosmith, co-written with Danny Fields, was published. Not long after the book was released, Foxe announced that the paperback edition of Dream On would include nude photos of Steven Tyler, but Tyler won a lawsuit in 1999, preventing Foxe from publishing the photos. In 2000, she launched a web site in which she was selling nude pictures of Tyler, but by the end of the year, the site closed.
Foxe died from an inoperable brain tumor on September 7, 2002.
