Jennifer Aniston has revealed that her fiance Justin Theroux is a bit of a prankster. The ‘Friends’ actress said in an appearance on ‘The Ellen DeGeneres Show’ that Theroux calls it trickery, the New York Post reported. She said that the 41-year-old actor constantly hides behind the drapes and she is constantly scared. “It’s like, it doesn’t get old on me,” Aniston added. When DeGeneres suggested that the 44-year-old bride-to-be should exact revenge, Aniston replied saying that she is going to do that.
