Jake Gyllenhaal (wearing the ape suit) and Reese Witherspoon (dressed as a witch) had another public play date Wednesday, taking Witherspoon’s two children, Ava, 8, and Deacon, 4, trick or treating in L.A.’s Brentwood neighborhood.

“They were holding hands and swinging them in the air as they walked around the neighborhood,” adds a witness, who says 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 witch wardrobe) and Deacon (dressed as a super hero) ran up to every door for treats, “Reese and Jake waited on the sidewalk and flirted,” the onlooker tells Usmagazine.com. “Jake tapped Reese on the butt and then she hit him back - they began running a circle hitting each other!” the witness says. “Then Jake picked Reese up off her feet and she screamed.”

Gyllenhaal seemed to play it cool during his first public outing with Witherspoon’s children.

“Jake ran up to Deacon with the gorilla mask and pretended to scare him!” the onlooker says. “Deacon laughed.”

Last week Reese and Jake attended actress friend Kate Hudson’s Halloween party at her Pacific Palisades mansion Saturday night.

Also in attendance at Kate’s party: On-again flame Dax Shepard, Will & Grace’s Sean Hayes and comedian David Spade.
