Nipsey Hussle's longtime girlfriend Lauren London broke her silence following his shooting death, just hours after authorities arrested the rapper's suspected killer. London, an actress and the mother of Nipsey's 2-year-old son, shared a heartbreaking message on Instagram. "I am completely lost. I've lost my best friend," the mom wrote. "My sanctuary, my protector, my soul. I am completely lost without you. We are lost without you babe. I have no words."
