Paris showed up for David Letterman's show this afternoon and was very conspicuously followed by a guy with a camera who even helped touch up her hair. Even on the fly, Paris gets her hair did.
As for her return engagement with Dave, we're told that Letterman -- who made Hiltie "sad" the last time she was there by bringing up her slammer stint -- actually gave her flowers.
UPDATE: Mystery solved! That's Jason Moore, her manager, videotaping her. He's shooting a documentary about Paris.
