Britney Spears's aunt Sandra Bridges Covington, with whom she had been very close, died of ovarian cancer on January 21, 2007. Spears then stayed in an off-shore dru-g rehabilitation facility in Antigua for less than 24 hours on February 16. The following night at a hair salon in Tarzana, California she shaved her head with electric clippers. A few days later, she admitted herself to another treatment facility in Malibu, california. While leaving the facility briefly, she quickly returned on February 22. The previous day, Kevin Federline had requested an emergency hearing regarding the custody of their children but then his attorney announced that Federline asked to cancel the court appearance. No further explanation was given. Throughout 2007, Spears's behavior received heightened media attention, including attacking a paparazzi vehicle with an umbrella. Spears left the rehabilitation center on March 20 according to her manager, who said she was released after "successfully completing their program." As the legal battle over the custody of their children continued, many members of her entourage have been summoned to testify about her parenting skills.
