Sir Paul McCartney's ex-wife Heather Mills has gone from judgment to judge after landing an expert role at the upcoming Miss U.S.A. pageant just days after winning $49 million (GBP24.5 million) in a London divorce court. The former glamour model-turned-activist has signed on to judge beauty queens at tycoon Donald Trump's annual parade of lovelies in Las Vegas. Osmond siblings Donnie and Marie will host the show at the Planet Hollywood Resort + Casino next month (11Apr08). Mills, who became a U.S. TV star last year (07) when she competed in talent show Dancing With The Stars, won $33 million (GBP16.5 million) cash and assets worth $15.6 million (GBP7.8 million), following the breakdown of her four-year marriage to the former Beatle on Monday (17Mar08). She lost an appeal at London's High Court on Tuesday (18Mar08) when she attempted to stop details of the case from entering the public domain.
