Robert Pattinson and Kristen Stewart in Halloween Costumes

Robert Pattinson and Kristen Stewart held hands as they got in the Halloween spirit at a party held at the Hollywood Forever Cemetery in LA last night. The couple, who wore matching masks, held hands as they made their way through the spooky spot. Kristen later changed her costume to a bright pink wig and sunglasses. Rob and Kristen were seen kissing during the bash, which also included Katy Perry. There has been plenty of celebrity Halloween fun since stars kicked off celebrations last weekend, and the excitement continued last night with trick-or-treating and costumes in LA, London, and even NYC.
