ETOnline has posted these pics of Britney Spears losing it with the paparazzi last night outside Kevin Federline's house (and who can blame her, really). Spears was likely hoping to see her two sons, who were holed up inside with their dad - who refused to answer the door to the popstar. Spears reportedly spent about 45 minutes outside the house before being picked up by her mom and eventually taken back to rehab.
