Kristen Stewart and Robert Pattinson Wear Creepy Transparent Masks For Halloween (PHOTOS)

Robert Pattinson and Kristen Stewart stepped out for Hollywood Forever Cemetery’s Halloween party on October 31, and instead of going all-out with their costumes like other A-listers, the recently reconciled pair kept it simple — and serial-killer freaky — in clear masks.

"They snuck in the back of the party and were wearing normal clothes, but grabbed masks from a photo booth and put them on [seemingly] so people wouldn't recognize them," a source tells PEOPLE. "They were holding hands, and at one point, he put his arm around her. She [didn't seem] as affectionate towards him."
