We're used to seeing blonde babes and film crews stopping by Kevin Federline's house - but Britney Spears' parents?! Not so much! We caught Jamie and Lynne arriving K-Fed's Tarzana estate on Friday afternoon. We also caught K-Fed's lawyer Mark Vincent Kaplan showing up a little while later. Might Britney's folks have been meeting with Team K-Fed to plan a few more strategic legal maneuvers? Whatever they were up to, nobody was in the mood to talk about it - but we'll certainly let you know if we hear anything!
