Molly Sims brought her Halloween party to her LA driveway this year.

She decked out a luxury Airstream, from RV-rental site Outdoorsy, decorating it with “life-size skeletons and balloons … They even had a ‘rotten candy bar,’ and the kids snacked on mummy-wrapped hot dogs,” a pal said.

Sims, who’s married to Netflix exec Scott Stuber, and her brood also told ghost stories and screened scary flicks.
