Jake's and Reese's Halloween Night

The romance between Jake Gyllenhaal and Reese Witherspoon is really blossoming as the two were spotted out together last night with Witherspoon’s two children, Ava and Deacon.

Reese was dressed as a witch and Jake was dressed as an ape. The two had taken Witherspoon’s kids trick-o-treating in the Brentwood area.

"They were holding hands and swinging them in the air as they walked around the neighborhood," a witness told Us Weekly. "Reese was laughing at everything Jake was saying."

When the kids were going to houses to get treats Jake and Reese would reportedly stay behind and flirt on the sidewalk.

"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."

Don't they seem like two high-school kids in puppy love?
