Isla Fisher and Sasha Baron Cohen
Huh? Married couple Isla Fisher and Sacha Baron Cohen took a different approach to Halloween by throwing on just about anything! Fisher wore a red wig, a pink tutu and a tiger mask out while Cohen wore a monkey mask and carried a doll. The two were seen arriving at the Casamigos Halloween Party in Beverly Hills, Calif., on Friday, Oct. 25.
