ISLA Fisher and her funnyman fiance Sacha Baron Cohen are reportedly set to tie the knot later this month. The pair - who have been together for eight years - was due to wed in August 2006 in Italy, but they called it off because Isla, 34, had not completed her studies. But a British newspaper claims the couple is planning to get married on February 26. Fisher and Cohen have reportedly have sent out notices to 80 guests telling them to keep 26th free and have reserved several venues to ensure that the event remains top-secret. SS Sacha and Isla are throwing a party. They have asked everyone to come in fancy dress, a source said, adding, They havent told the guests its a wedding but thats what we all suspect.
