MUMBAI: Following in the footsteps of Katy Perry, Miley Cyrus, Justin Bieber and The Jonas Brothers, songstress Beyonce Knowles is in plans to direct, produce and star in a feature film documentary on her life and career.

The singer and her representatives have been pitching the idea to Hollywood studios of a non-fiction film about the celebrity's life and career.

The star has already released a mini documentary entitled 4, which showed the making of her successful album and gave a rare glimpse into an otherwise very private life.
