Coachella 2014 took over Palm Springs, Calif., this past weekend and will take it over again this weekend. Solange Knowles looked excited and surprised as her sister, Beyoncé Carter, made a guest appearance for an impromptu rendition of “Losing You.” Both were rocking big and bold natural hairstyles, with Solange in a beautiful orange one-piece short set and boots, and Beyoncé in a printed short set, boots and a black hat. Check out more photos of the two in the gallery. –joi pearson @joiapearson
