Troubled singer Britney Spears has fired her latest assistant, according to U.S. reports. The woman, known only as Carla, has been a constant presence at Spears' side throughout recent weeks, but has now reportedly been sacked by the Toxic hitmaker after being accused of talking to the press. Carla - Spears' one time housekeeper - is said to have been fired by Spears' companion/manager Sam Lutfi, who suspected she was revealing intimate details of the star's life to the media. A source tells celebrity blogger Perez Hilton, "Carla used to be Britney's maid. One day, Britney just decided on a whim that Carla should be her assistant." Another of Spears' assistants, Kalie MAChado, sold her story to a U.S. magazine last year (07) revealing her insight into Spears' life around the time of her famed head-shaving incident in February 2007.
