Please, don't be alarmed. Britney Spears' face is NOT twisted into a mask of indescribable suffering because she's in the thrall of a fiery attack of an STD that Kevin Federline "forgot" to tell her about—she's merely desperate to use the toilet at a Malibu Jack in the Box. Other photos in the series seem to reveal that Spears' bladder-voiding needs were so urgent that she forgot to remove her shoes before entering the public bathroom, but it's anyone's guess as to whether they remained on once she was in the safety of her own stall.
