Britney Spears BritneyPhoneKfedHouse.jpgX17 is with Brit right now and she just picked up some take-out from Sharky's... literally one block away from Kevin Federline's Tarzana home!

Brit's day started at her Bel-Air home, and after that she traveled (with her assistant) to her home in Malibu. Finally she ended up at Sharky's - but why all the way out there? X17 can also confirm that did not seem like her usual chipper self. The Gimme More singer was arguing with someone on the phone, looking upset and nervous (much like in the archive pic above). What's wrong?

Britney's next destination? We'll stay with her - more details coming!
