It was 80 degrees and muggy in Manhattan yesterday, but it sure was freezing over at "The Late Show with David Letterman" -- and we don't mean the infamously cold Ed Sullivan Theater.
First, Kevin Smith showed up in his trademark floor-length coat-cape, and obligingly posed with fans and signed autographs.
That was just a little more than "Private Practice" star Kate Walsh could manage, as she gave but a passing glance at photogs and sped past a screaming crowd of admirers without so much as a smile -- inducing a big groan from the hoard. Nurse!
We're told that Kate was early for her spot on the show, and had plenty of time to sign. When she left, she did pose for a few pics ... and her rep tells us that she signed autographs as well!
