New York, November 29-30 – Jessica Simpson left the lights on all over New York this week. On Tuesday, the Newlyweds star overbooked, performing live on television with hubby Nick Lachey at Rockefeller Center’s big tree lighting ceremony, singing her last number just before the lights went on at 8:55 P.M. Meanwhile, she was scheduled to appear at 8:30 P.M. over at MTV studios on Times Square to flip the switch on a giant Mitsubishi Electronics screen. Live TV won out; the folks at MTV cooled their heels waiting. Nick flew out to L.A. following the Rockefeller Center tree gig to be at VH1’s Big in ’04 show the next day.
