Not very much is known about Lacey, due to her limited appearances. She likes to ride horses like Mia, and does ballet like Stephanie. Her personality is a somewhat mysterious, having shown multiple sides in the show.
In "New Girl in Town" she was arrogant and unthoughtful. Yet in "Stephanie's Surprise Party" Lacey showed a more caring side, she buys Stephanie a present and is a friend to her when Stephanie feels her friends have let her down.
