"Real Girl" is a song written by Lenny Kravitz, Niara Scarlett, Matt Ward and Dean Gillard.
The track was up against Buena's former bandmembers, Sugababes, as well as Leona Lewis, Kate Nash and Take That.
The video shows Buena laying on a bed, writing and looking at pictures in what appears to be a scrapbook.
She is then seen singing and wearing a white dress in a totally new background with pictures on the wall.
She is wearing a short black dress, as seen on the single cover, and singing when the second chorus starts.
