Solange Knowles hates the way she looks when she sings. The 23-year-old singer - sister of "Halo" star Beyonce - stopped halfway through her performance at the Essence Music Festival in New Orleans last weekend and demanded a paparazzo stop taking photos of her.

As the audience looked on in amazement, Solange shouted: "Mr. Photographer, you are making me self-conscious. I swear I make the same stupid three faces over and over again, so please leave me be."
