Britney Spears threatened to sue a Florida radio station unless they removed billboards of her with a shaven head.
Lawyers for the 'Toxic' singer told WFLZ radio to take down adverts featuring three pictures of the 26-year-old singer bald and snarling.
The singer's legal team claim images of Britney can only be used for promotional purposes with her consent.
A letter was sent to station owners Clear Channel Communications from law firm Lavely and Singer dated June 14.
It read: "Clear Channel was already exposed to substantial liability for its offensive, unauthorised commercial exploitation of my client's photograph on the billboards.
"Once again, we demand the immediate removal of the billboards, confirmed by documentary evidence and verified under penalty of perjury."
The pictures were taken as she attacked a photographer's car with an umbrella, the night before she entered Malibu's Promises rehab facility.
The billboards featured three identical pictures of the singer next to the radio station's logo and a picture of talk show host Todd Schnitt.
Above each picture were the slogans "Total nut jobs", "Shock Therapy", and "Certifiable".
Schnitt revealed Clear Channel have now removed the billboards, adding, "I'm not happy with that".
