While Gaga, 26, is convalescing following hip surgery, Kardashian apparently has been busy convincing Nicola Formichetti to work for her.
The pregnant star has bombarded Gaga's collaborator with emails and even took a last-minute flight from Miami to New York to meet up with him, reported Sun online.
The 'Poker Face' hitmaker, who was forced to axe the remainder of her Born This Way Ball tour after a case of joint inflammation condition synovitis left her unable to walk, has not taken well to Kardashian encroaching on her territory.
