Madison Mildred Cooperstein is a recurring character on The Secret Life of the American Teenager.
She is Catholic, on the yearbook staff, and seems to be an only child. She is best friends with both Lauren Treacy and Amy Juergens, but is closer to Lauren. She and Lauren feel that Amy began ignoring them after she became pregnant and got together with Ben. It is revealed that she eventually married Jack Pappas. She is portrayed by Renee Olstead.
She is introduced in Falling in Love as the best friend of Amy Juergens and Lauren Treacy. She runs up to Amy and, along with Lauren, tells Amy about the 'delicious, single new counselor' Marc Molina. She and Lauren are the first to know about her sex with Ricky and pregnancy. Madison began dating Lauren's brother, Jason in season one, but they broke up during the summer of 2009 because Jason thought she was "too casual about her future". It turns out that Jason was jealous about Madison hanging out with Jack over the summer, and Jason had had a fling with Grace.
Madison is currently having sex with Jack Pappas, but is unsure if she wants to continue. Madison doesn't like being alone and she prefers to have classes with all of her friends.
It is also revealed that Madison's mother passed away years ago and she lives with her father and his new wife, Emily, who she previously referred to as "Wicked Stepmother."
She worked at the food court at the mall over the past summer and there she met Stanley, and broke up with Jack again. She tells her dad that she and Stanley couldn't date before because he was her boss. She says that he's 20, and still in high school, and had been married before. When Morgan and Emily (her parents) meet him, they hate him, and after her dad tells him to leave, he tells Madison that he (Stanley) must be at least 30. Madison claims that she likes him anyway, and that Stanley thinks she's pretty, smells nice, is not interested in having sex with her, and that she has a nice body. Her father is very angry with her and tells her that she can't see him.
