He tried to avoid being subpoenaed for as long as he could, but Britney Spears's friend/manager, Sam Lutfi, was finally deposed yesterday by Kevin Federline's lawyer, Mark Vincent Kaplan. According to E! News, Sam was questioned on Brit's drug use and whether he helped her strike a deal with paparazzi agency X17, so that they pay her for pictures of her daily life. However, a friend of Brit tells E! News that she has nothing to worry about: "Sam would never sell Britney out. There is no bigger supporter of Britney than Sam. I can't imagine Kaplan is going to get much out of him."
