On Sunday's episode, Kim talked about how Rob inked over his ex- girlfriend Adrienne Bailon with Rita Ora’s name who is also now in fact an ex!

"He covered it with a life-sized barbie doll of Rita that has now turned into a Cabbage Patch Doll," Kim said laughing. "Have you seen it lately? It was like a Barbie doll and he's gained weight and it’s like a huge Cabbage Patch Kid. Huge!"
