The music video for “Only Girl” was directed by Anthony Mandler and premiered online on October 13, 2010. In an interview with Just Jared, Rihanna explained the filming of the video and the video’s simplistic theme:
“It’s really, really beautifully shot in these crazy, crazy, crazy places, We shot landscapes that we found a couple hours outside of L.A. It looks so unreal. It looks fake, like something out of a postcard with the beautiful hills… We had a lot of sunshine those couple of days, so it really worked with the whole essence of the video. But really, the video just shows this big landscape and the only person there is me.”
The video mimics the carefree lyrics to the song, which suggest that she is the “only girl in the world”. The majority of the video features Rihanna prancing around hillsides wearing a mohair sweater and shorter skirt, a bustier and mini floral skirt, and lastly, a white bra and “boy shorts.” The video uses the simplistic theme of predominantly focusing on Rihanna frolicking on a hillside with life size flowers placed near her with an array of artistic sceneries and props. Other scenes include Rihanna surrounded by multi-colored balloons, riding on a swing that hangs from the sky, lying in a bed of flowers and then dancing in front of a tree covered with blinking lights that adds to the surreal imagery.
