Kristina Bobby's granma blasts 'incestuous' relationship with Nick

I previously posted an article about Bobby Kristina and Whitney's unofficially adopted son who lived with her for 12years. Her grandmother (Cissy) as declared their relationship as being incestuous because Nick grew up together with her after Whitney took him in at the age of 12 when his father went to prison and his mother was unable to take care of him. See Picture below.
