IN light of Larry King‘s latest divorce, CNN staffers are cackling that the long-lived anchor is even less likely to leave the network. “He can’t quit because he owes alimony to so many different wives,” one insider said. King has been married eight times, twice to one woman. His latest, Shawn Southwick, mother of two, will go for half of King’s fortune since there is no pre-nup. Shawn, 50, charges that King, 76, slept with her sister Shannon, 46. King, who’s worth $144 million according to a report, is now in the middle of a four-year, $56 million contract. His rep had no comment.
