About Katie Cassidy

Katherine Evelyn Anita "Katie" Cassidy is an American singer and actress best known for her role as Ella Simms in the short-lived remake of The CW’s television series Melrose Place. Her other notable appearances include Supernatural, and Gossip Girl, as well as the films Black Christmas, Taken, and A Nightmare on Elm Street, which was released in theaters April 30, 2010.

Cassidy was born in Los Angeles, California, the daughter of actor David Cassidy and model Sherry Williams, who first met and dated Cassidy in early 1970. Sherry and David separated but remained close friends. Cassidy's paternal grandparents were actors Jack Cassidy and Evelyn Ward. She grew up in Calabasas, California with her mother and stepfather, Richard Benedon, an ER physician. She has two older sisters, Jenna and Jamie. She also has a younger half brother Beau Cassidy.

While in elementary school, Cassidy became interested in show business and participated in several community theatre productions beginning at the age of 7, and as a teenager studied with an acting coach. She did some modeling which culminated in a campaign ad for Abercrombie and Fitch in 2004. Her mother would not allow her to act professionally until completing her high school education with college prep courses.

In 2006, she appeared in supporting roles in films such as When a Stranger Calls and Click. Click opened at #1 at the box office with $40 million. She also starred as the protagonist, Kelli Presley, in Dimension Films remake of the 1974 film Black Christmas. The film was released throughout late December 2006 and grossed $21 million.

In 2007, she appeared in supporting roles in films such as Walk the Talk, You Are Here (later renamed to Spin), and Live! in which she played Jewel Jensen an aspiring actress looking her big break in Hollywood. That same year, she filmed numerous scenes in the film remake Revenge of the Nerds alongside Adam Brody and Jenna Dewan. Production was halted and the movie was eventually cancelled.

In 2008 she appeared as Amanda in Taken and had a recurring regular role on The CW's Supernatural as Ruby.

In 2009, Cassidy appeared as Patricia 'Trish' Wellington in the CBS mini-series Harper's Island. It was also in this year that Cassidy signed on as a series regular on The CW's reboot Melrose Place of the 1990s drama series of the same name. She played Ella Simms, a publicist who works at Amanda Woodward's company. The media has drawn similarities from Cassidy's character and Heather Locklear's character, Amanda. Her role as Ella has drawn positive critical comment from the Los Angeles Times who wrote: "Cassidy is already being singled out as the show's deliciously devious one to watch" and has been cited as "the best thing about the Melrose reboot" by New York magazine. The series premiered September 8, 2009 and was cancelled after one season.

Cassidy also joined the cast of the remake of the horror film A Nightmare on Elm Street. She played Kris Fowles, friend to lead character Nancy Holbrook (Rooney Mara) and victim of Freddy Krueger. Filming began in Chicago and was released April 30, 2010. Cassidy was nominated for a Teen Choice Award in the "Horror/Thriller Actress" category for her role which she lost to Megan Fox.

Cassidy was cast romantic comedy Monte Carlo which was filmed in in Monaco, Budapest and Paris.

She is a spokesperson for the charity H.E.L.P Malawi.
