'RHONY' Newbie Daisy Dragged By Costar Over Longtime Boss Martha Stewart

6/24 -- 5:33 AM PT -- Daisy Toye tells TMZ ... "There is no truth or validity to any of these statements regarding my career or my relationship with Martha Stewart. I am confident the show will allow audiences to see the pride I take as a makeup artist. My professionalism and determination in the beauty industry bring me much pride."

She continues, "My love and devotion to Martha and our relationship transcend friendship and work, Martha is my family. I am so excited for the audience to see for themselves how dynamic this season will be and to enjoy watching the truth regarding my career and long-term relationship with Martha."

Martha Stewart’s longtime makeup artist, Daisy Toye, ruffled feathers during production on her first season of "The Real Housewives of New York" ... due to pals believing she wants to trade her job with Martha for her fifteen minutes of fame ... TMZ has learned.

Sources close to production tell TMZ ... Daisy has made it clear behind the scenes that she hopes to launch a new career with 'RHONY' … which will let her stop working with Martha, whom she has been working with for 2 decades.

One source told us they felt Daisy was planning to leave Martha "high and dry" for fame.

We're told Daisy's loudest critic was her costar Sai De Silva ... she knew Daisy for years before the show and called her out during production. Our sources tell us Sai, who is going through her divorce, claimed Daisy had an elitist attitude and wasn't supporting her through her personal issues.

Our sources say Sai finds Daisy's behavior "gross" and dragged her for filth during the seaspm. 

During filming, the cast asked Daisy if she was in Martha's will ... and our sources say Martha will be shocked when she sees what happens on screen.

One source said ... "It's not a good thing."
