Angry Britney Spears Declares 'I Quit' On Social Media, Attacks Sister

The singer lashed out at her sister for performing remixes of her own songs. "My so-called support system hurt me deeply!!!!" she wrote on Instagram.

A clearly fed-up Britney Spears told the world Saturday “I quit!” and attacked her sister amid her battle to free herself from her father’s legal control of her professional and personal life. The pop star, 39, vowed she’s not planning a quick return to the stage as she fights to end the conservatorship run by her dad. “I’m not gonna be performing on any stages anytime soon with my dad handling what I wear, say, do, or think ... I’ve done that for the past 13 years,” Spears wrote on Instagram.
