Australian actress Isla Fisher has vowed to never work with her fiance Sacha Baron Cohen, because it will be "the kiss of death". The Wedding Crashers star, who is expecting her first child with Cohen later this year (07), insists she will never star in the same movie as the Borat actor. She says, "God, no! I mean, how successful are married working relationships? Nicole and Tom split up after Eyes Wide Shut ... I feel like working together is the kiss of death."
