Reese Witherspoon and Jake Gyllenhaal may not have confirmed their romance, but the two Hollywood heavyweights have nevertheless been spotted unashamedly flirting.

The pair were apparently holding hands and giggling as they accompanied Reese's two children, eight-year-old Ava and four-year-old Deacon, while they trick or treated on Wednesday (October 31st).

The 31-year-old actress, dressed as a witch, was spotted laughing and screaming as the 26-year-old Brokeback Mountain star chased her around the Los Angeles neighbourhood of Brentwood.

"They were holding hands and swinging them in the air as they walked around the neighbourhood," a source told

"Reese was laughing at everything Jake was saying.

"Jake tapped Reese on the butt and then she hit him back - they began running a circle hitting each other! Then Jake picked Reese up off her feet and she screamed. Sometimes he came up from behind and nuzzled his big hairy mask into her neck."
