Portia Doubleday (born June 22, 1988) is an American actress. She is perhaps best known for her roles in the 2009 film Youth in Revolt as Sheeni Saunders and in the 2011 film Big Mommas: Like Father Like Son as Jasmine Lee and later in the 2013 film version Carrie as Chris Hargensen.
Doubleday was born and raised in Los Angeles, California, the daughter of Christina Hart and Frank Doubleday. She grew up in a show business family: her parents are former professional actors, and her older sister, Kaitlin, is also an actress. Her mother now works in the entertainment industry as a writer, and also produces plays. Doubleday attended the Los Angeles Center for Enriched Studies, a magnet school in west Los Angeles.
Doubleday first appeared in a commercial for Goldfish crackers at the age of eight, and had a small role in the film Legend of the Mummy (1997). Her parents insisted that she finish high school before pursuing a career in acting. Doubleday was cast in the pilot episode of United States of Tara, a television series created by Diablo Cody. Doubleday played 15-year-old Kate, the daughter of Toni Collette's character. Doubleday was replaced however, when the series' creative team chose to go in a different direction with the character. She appeared in the short film "18" in 2009, about a girl dealing with the end of her mother's life.
As of January 2010, Doubleday studies psychology in college and was considering pre-med. She described herself as a "tomboy" to the Los Angeles Times; Doubleday played soccer for twelve years.
