Reese and Jake's spooky PDA

Jake Gyllenhaal and Reese Witherspoon had another PDA-packed public date Wednesday, taking Witherspoon's two children, Ava, 8, and Deacon, 4, trick or treating in LA's Brentwood neighborhood. Witherspoon was dressed as a witch; Gyllenhaal as an ape. "They were holding hands and swinging them in the air as they walked around the neighborhood," says a witness, who added that Gyllenhaal often lifted up his gorilla mask to smooch his Rendition co-star. "Reese was laughing at everything Jake was saying." As Ava (also in a witch costume) and Deacon (a superhero) ran up to every door for treats, "Reese and Jake waited on the sidewalk and flirted," the onlooker says. "Jake tapped Reese on the butt and then she hit him back - they began running in a circle hitting each other!" the witness reports. "Sometimes he came up from behind and nuzzled his big hairy mask into her neck."
