What's Got Britney Smiling?

Only Larry Rudolph knows for sure!

We caught Britney Spears swinging by Bally yesterday afternoon for her daily workout regimen. Of course, Brit's visit wasn't all pleasure - as soon as we saw her manager Larry show up, we knew she was gettin' down to business, too!

But whatever the two talked about, it clearly didn't bother Britney - in fact, the pop princess left with one of the biggest smiles we've seen on her face in recent months! Might she have been strategizing for her comeback with Larry? Or could she still be in "vacation mode"?

Either way, we've put together a gallery of Britney below - check it out!
