Danielle Van de Kamp (formerly Katz; Joy Lauren) is the daughter of Bree and Rex Van de Kamp. She is also Andrew's younger sister. Danielle appears to need a boyfriend in order to feel good about herself, and is preoccupied with her looks. During her sophomore year, Danielle was the head of her high school's abstinence club. However, Danielle is planning to lose her virginity to her ex-boyfriend, John Rowland, to lure him back to her, but John permanently ends the relationship at Bree's request, leaving Danielle devastated and heartbroken. This is also the first step towards Danielle acting more strained around her mother because she thinks she will get more attention from her parents if she behaves like her brother.
