FIRST OFF . . .

Joan Rivers, the recently dismissed host of Fox Broadcasting Co.’s “Late Show,” will be returning to Fox . . . well, sort of. Fox has announced that Rivers is on the list of presenters Sept. 20 for the 39th annual Emmy Awards, recently wrested away by Fox from its traditional home on Big Three network TV. Rivers’ press representative, Richard Grant, insists that her participation is appropriate: “It’s not like this is a Fox Broadcasting party--these are the Emmys,” he said. “She is a leading lady of television, and she should be there.” Grant added that Rivers harbors “no animosity” toward Fox. FBC President Jamie Kellner said Rivers was selected by Emmy producer Don Ohlmeyer. “We are endorsing his selection,” he added.
