We caught the pop princess stopping by Bally yesterday afternoon for another workout. As you can see, Britney was really feeling the chilly weather - she had to break out her big, puffy down jacket to keep warm!

(Of course, the low temperature wasn't the only chill in the air - wait'll you see the icy demeanor on the Bally employee tasked with marshaling the paps!)
