The couple will tie the knot in Sydney, Australia. Most reports listed the Mary MacKillop Catholic Church as the venue, but one source is stating otherwise. According to theage.com.au, an Australian news service, the hot tip is now the Cardinal Cerretti Memorial Chapel, a Gothic-style church in St. Patrick’s Estate, which overlooks the Pacific Ocean. The story adds that a reception center near the church could easily hold the reported 200 guests, set to include media titan Rupert Murdoch, actors Russell Crowe and Naomi Watts and record producer Dann Huff. Additional sources say that the guests will only be given 24 hours’ notice as to where the wedding and reception will take place.
