Chrissie was the wild younger sister of supermodel Jean Shrimpton. She became the subject (or target) of many Stones hits during and after their stormy 3 year relationship ended.

The song “19th Nervous Breakdown” commemorates the couple’s first acid trip together. Chrissie did not handle the acid well triggering a fit of paranoia. The song “Under My Thumb” is misogynistic tune which implies that Jagger has finally tamed the wild confident girl into “the sweetest pet in the world”.

The couple broke up in late 1966, and Mick immediately began a relationship with Marianne Faithfull. Three days after their ending fight Chrissie took an overdose of sleeping pills; medics saved her life and pumped her stomach. Jagger got the hospital bill and refused to pay it. He had all her possessions boxed, and sent to her.

The final blow came two weeks later, when the song “Lets Spend the Night Together” became a transatlantic hit. It had been written after Jagger’s first night with Marianne.

Under my thumb
The girl who once had me down
Under my thumb
The girl who once pushed me around

The difference in the clothes she wears
Down to me, the change has come,
She’s under my thumb
Ain’t it the truth babe?
