Britney Spears BSPEARS073007_22.jpgLooks like Alli won't have to worry about loneliness when she heads down to the courthouse - according to Us Magazine, Daimon Shippen, Britney's other constant companion, got hit with a subpoena last night! The magazine specifically quotes a source in Kevin Federline's camp as describing Shippen as having "a unique position having worked with Britney for a long time and has incredible knowledge of her parenting skills and comings and goings." Of course, our source says Britney's a big-time hands-on mother - looks like this custody battle's going to be one for the ages!
