Vanessa Lachey's three children dressed up as little NCIS agents, while she and her husband Nick Lachey posed as prisoners for Halloween. The actress was touched when her daughter said she wanted to "be like Mama," and cherished the moment forever. The family has been sharing sweet moments while living in Oahu, where Vanessa films NCIS Hawaii. In an appearance on The Ellen DeGeneres Show, Nick explained that his kids didn't think he was cool until he competed on The Masked Singer. He joked that it took dressing up like a pig and singing on national television to be cool to his kids.
