When it comes to friendship, Hills costars Lauren Conrad and Kristin Cavallari might not always see eye to eye. But when it comes to Halloween, the former frenemies are on the same cute-costume page: Minnie Mouse! With baby Camden at home, Cavallari tried on mouse ears and gloves while hosting the Bing It On Halloween Costume Challenge in New York City on Friday. Wearing shorts and sky high Louboutin heels, the new mom, 25, added her own sexy twist. Last Oct 31., Conrad, 26, donned a similar costume for a party at the Hollywood Forever Cemetery. Complete with whiskers painted on her face, Conrad’s costume couldn’t have been cuter. The Paper Crown designer recently spoke to Allure magazine about her time on The Hills. “I think the story they told wasn’t a dishonest one,” she said. “They way they did it sometimes was. They aren’t going to be there for everything. Sometimes two of their main characters will get into a fight and that’s important to the story line.” So tell us in the comments below: Whose mouse do you want showing up at your house this Halloween?
