Disguised in a halloween mask, pop super star Britney Spears takes revenge on the paparazzi along with her sister,Jamie Lynne (red t-shirt) and two friends, by throwing vanilla milkshakes at them after stopping off at a local fast food restaurant in Kentwood,Louisiana. The group were driven by Britney's mother Lynne. Britney is spending her honeymoon in her home town with husband Kevin Federline. Britney Spears went undercover, literally, as she and wore a "Scream"-style mask during an outing in Kentwood, Louisianna where she and new "husband" Kevin Federline are honeymooning! Spears is recognizable by her tatoos -- she, her mom and some friends went to Nyla's Burger Basket for lunch, while Federline went shopping for shooting supplies at Wal-Mart with a bodyguard and then to JC Penney department store, looking for more shoes to add to his infamous collection of high-top Nikes. Amid speculation about the legitimacy of their wedding, the pair, though separate here, seemed to be having fun with Britney's family.
