They had her mother’s initials tattooed on their wrists earlier this month. And now Whitney Houston’s daughter Bobbi Kristina and her brother-turned-boyfriend Nick Gordon have once again been inked. The couple showed off their new body art in a series of new Twitter pictures. Cuddling up on the bed together, Bobbi Kristina, dressed in a revealing blue lace crop top and grey tracksuit bottoms, displayed a music note design on the side of her stomach. Nick, meanwhile, has revealed a lion design on his right bicep. The pair, who lived together as brother and sister for more than a decade before their mother’s death, are seen looking extremely intimate in the snaps.
