“While Bill Hemmer is walking out the door at CNN, his new girlfriend, Kimberly Guilfoyle Newsom, is walking in,” according to Page Six. “Last week, Court TV honcho Henry Schlieff and CNN head Jonathan Klein had lunch at Michael’s. Insiders say they discussed how well the ‘sharing’ of Nancy Grace on both networks was going, and that ‘Kimberly is next.’ Newsom, the comely ex-wife of San Francisco mayor Gavin Newsom, currently anchors ‘Both Sides’ on Court TV.” Only one snag: Remember the recent Newsweek story? “Klein declined to comment on Grace, saying Headline News does not fall under his jurisdiction.” So is Newsom destined for a spot on CNN/U.S.?
