Lady Gaga is reportedly furious after learning that Kim Kardashian has poached her designer Nicola Formichetti.
While the singer is convalescing following hip surgery, it's claimed Kim has been busy convincing Formichetti to work for her.
The reality TV star apparently bombarded Gaga's collaborator with emails and even took a last-minute flight from Miami to New York to meet up with him.
And her efforts have apparently paid off, according to US reports.
It's alleged that the Poker Face chart-topper has not taken well to Kim encroaching on her territory, the Sun reported.
A source told Ahlan! Magazine that Gaga was fuming when she discovered Nicola was working with Kim since she's fiercely protective of the people she works with and has always been determined to have Nicola all to herself.
