Pallenberg was born in Rome in 1944 and grew up dividing her time between the Italian capital, Germany and New York City, before settling in London. According to reports, it was when Keith saw Brian hitting Anita when they were on holiday in Morocco in 1967 that he stepped in, put Anita in his auto and took her back to England. The 5-foot-9 Ms. Pallenberg was the same size as Richards, who sometimes were her gender-bending outfits onstage. The Stones songs "Angie" and "You Got the Silver" were written about Pallenberg. I will love you forever, dearest Anita. She took an active role in shaping their look and sound, as the music critic Nick Kent pointed out, "Anita's influence on Keith was instant".
Pallenberg was born on April 6, 1942.
After being expelled from German boarding school aged 16, she began modelling, first in Italy and later in NY, where she spent time at Andy Warhol's Factory. The cause of death was not revealed, but the statement released Wednesday said Pallenberg "had been ill for some time" and that her family was by her side.

Writing in his book Up And Down With The Rolling Stones in 2010, Richards" former assistant Tony Sanchez also described her as the woman who "almost broke up the Rolling Stones'. The first time he did acid, Brian told her, "Dress me up like Francoise Hardy". Pallenberg then went to NY where she hung out with pop artist Andy Warhol.
