SAM IN A JAM

CBS News’ Dr. was among the wellwishers who showed up at the new Fifth Ave. office of Dr.

to celebrate the opening her new Wellness Center, only to find the doctor wasn’t in the house. Sam had been trapped in the traffic surrounding the Rockefeller Center Christmas tree lighting and arrived to her own opening day an hour late. We’re told Gomez had to go, but called later to wish her

well.
