Stella Mccartney refuses to grin in photos - because she hates the way she looks when she smiles. The daughter of music legend Sir Paul MCCartney blames being the family's second child for her hatred of cameras - because she didn't get as much attention as her siblings. She says, "I don't smile at cameras because I don't think I look very good when I smile. "There aren't as many pictures of me and no one pays attention to me. And I was always really offended. It's true that I don't like cameras but I'm not angry now, I'm cool."
