Beyonce Knowles is to star in a documentary about her life and career.

The "Crazy In Love" singer is to direct, produce and appear in the film which will include concert footage, backstage scenes and interviews with her and her loved ones about her life. The documentary will focus on the release of her 2011 album 4, as well as her marriage to Jay-Z and the birth of the couple's daughter Blue Ivy in January 2012.

The former Destiny's Child star has been presenting different Hollywood studios with 20 minutes of footage in a bid to find the right distributor. Beyonce has had experience of directing in the past thanks to her MTV mini-documentary Beyonce: Year of 4 which showed her in the studio working on new tracks.

The 30-year-old R&B superstar is now set to follow in the footsteps of Justin Bieber, Katy Perry and Miley Cyrus with the fly-on-the-wall concert movie. The star teased fans on her official website in July with a cryptic message, "Leave Your Footprint On 19 August 2012," which could be linked to the documentary.
