SWAPPED: Texas-born “Bridget Jones’s Diary” star Renée Zellweger, 33, has traded her $1.8 million Hollywood Hills pied-a-terre for a $6.8 million 1930s Bel-Air mansion, according to the L.A. Times. Her new pad reportedly has seven bedrooms and eight baths, a master suite with an office and a workout room, a library, a guest house, maid’s quarters, a pool and pool house, and loggia and gardens, as well as a front gate. . . . DIVORCED: Billionaire Sumner Redstone, 79, CEO of Viacom Inc. (which owns CBS, MTV and Paramount Pictures, among other holdings), and his wife of more than 50 years, Phyllis Redstone, have reached a settlement in the dissolution of their marriage, reports Reuters. Financial terms were not disclosed, but she had asked for $3 billion when she filed for divorce in 1999, according to court papers. . . . DIED: Veteran Hollywood animal trainer Frank Inn, 86, whose stables of celebs included movie mutt Benji and “Green Acres” star Arnold the Pig, died Saturday, reports the New York Post. Another Inn trainee was Tramp, the dog in the Douglas household in the ABC ’60s sitcom “My Three Sons.” . . . CLOSED: Traditional New York celebrity hangout the Russian Tea Room, 76, shut its doors for good Sunday night, a victim of the current financial climate and a wrong-headed $60 million renovation that was completed three years ago. The regulars — who included stars from stage, screen TV, Lincoln Center and Carnegie Hall (which was right next door) — abandoned their Tea Room once it hiked its prices into the stratosphere and sought the tourist trade.
