-----Dianna Elise Agron was born on April 30, 1986 in Savannah, Georgia, and was raised in San Antonio, Texas and San Francisco, California. She has been dancing since the age of three, focusing mainly on jazz and ballet, and she later began hip-hop dancing. She fell in love with musical theater as a child, often performing in local and school productions, and played Dorothy in The Wizard of Oz in fifth grade, and began teaching dance as a teenager.
She began her acting career by playing minor characters on TV series and films, such as Close to Home, When a Stranger Calls, The Romantics and Drake & Josh.
She also appeared in several episodes of Veronica Mars and Heroes.
She branched out into writing and directing with the result being the short film A Fuchsia Elephant, the story about an 18-year-old girl played by Agron who creates an ideal birthday party. She also played roles in films such as The Hunters, I Am Number Four and Glee: The 3D Concert Movie. In 2013, she is starred in the movie The Family.
Agron's most notable role to date is as Quinn Fabray, a high school cheerleader, on the Fox series Glee. Agron has won many awards and nominations thanks to this role.
Agron was the last primary actor to be cast, having won the role only days before the pilot began filming. Agron said in a 2009 interview pertaining to her casting session: "I nearly bailed on my audition for the show. I was so nervous.”
With her wholesome good looks, Agron certainly looked the part, but the producers wondered if she appeared too innocent. Agron said in an interview: "They told me to come back with straight hair and to dress sexier. Later that week, I started work."
Agron auditioned with Frank Sinatra's "Fly Me to the Moon.” Quinn is described by Agron as Rachel Berry's (Lea Michele) enemy, and "terrible, the meanest girl.” Quinn was originally conceived as the antagonistic queen bee head cheerleader, a departure from Agron's actual high school experience.
Several songs performed by Agron as Quinn Fabray on Glee have been released as singles, available for digital download, also featured on the show's soundtrack albums.
Agron made her musical debut at the end of the episode "Showmance,” performing Dionne Warwick's "I Say a Little Prayer.” Quinn's next solo was in the episode "Throwdown,” performing The Supremes' "You Keep Me Hangin' On.” The song was released on Glee: The Music, Volume 1.
In season three, Quinn sings her first solo number since the first season, "Never Can Say Goodbye" by The Jackson 5, which received mostly positive reviews. In February 2013, Agron hosted and performed "Dreams" and "What's Love Got to Do with It" featuring A House For Lions to the 1st "You, Me and Charlie" concert in Los Angeles.
