Reese, Courteney and More Dish on Their Frightening and Furry Halloween Costumes

Dave Allocca/Startraks They’re creepy and they’re kooky….at least Reese, Courteney, and McDreamy and their kids will be on Halloween. The famous Avon faces ringing your bell that night won’t be making a sales call, but rather, they’ll be trick or treating with their children. “My son Darby is into skeletons and anything with skull and crossbones,” presenter Patrick Dempsey told PEOPLE at The Avon Foundation for Women Benefit at Cipriani 42nd Street in New York Tuesday. “They’ve been practicing for Halloween for about a month now.” And their daughter is also going for the dark side. “My daughter is going to be the gothic princess skeleton,” added McDreamy’s wife (and Avon’s Global Creative Color Director) Jillian Dempsey. “We’re going as the Addams Family,” chimed in Courteney Cox Arquette , also a presenter. And her little daughter Coco? “She’s going to be Wednesday,” said Cox, while husband David is going to be Gomez. Not everyone is that settled, as the evening’s co-host, Reese Witherspoon , claimed she didn’t know yet what the kids would dress as on Halloween. “But I’m going to be a monster,” said Witherspoon. “I found a great furry costume and I had to buy it.” And even those trick or treating without little ones are getting into the spirit, with Lauren Conrad making her own clown costume. “It just sounded fun,” she said. “And I figured it was the only costume that I could wear with flats. I can wear tennis shoes. You get tired of heels!“ – Jeffrey Slonim GUESS THE TRICK OR TREATER…BEFORE THEY WERE STARS!
