Lady Gaga is being sued by toy manufacturer MGA Entertainment for $10 million for an alleged breach of contact after the singer licensed the company to make a doll in her image.

MGA Entertainment claims the singer requested the removal of a voice chip from their Lady Gaga doll, which then jeopardised their ability to meet retail deadlines, reports the New York Daily News. The toymakers allege that Gaga and her team “engaged in intentional and deliberate delays” to postpone its launch until 2013, to coincide with her new album and perfume.

The company claims it sent prototypes to Gaga in March and the singer asked that the doll’s facial structure “be more supermodel-like.”

“Think a prettier version of Gaga,” MGA officials say they were instructed via emails. “Thin out the cheeks and sharpen the jawline. Give her more of a cat-eye and sexier, poutier lips.” After meeting Gaga’s demands, which also included a “Born This Way” zombie doll ensemble, MGA sent samples back to the singer in April, and that was when she allegedly asked that its voice chip be pulled. The singer then sent word that she wanted shipping delayed to 2013, despite MGA already making deals with distributors on its end.

Gaga’s spokesman Amanda Silverman told The New York Daily News the singer’s lawyers have yet to see the court papers.

This isn’t the first time Mother Monster has been sued. Last December, Gaga’s former personal assistant Jennifer O’Neill filed a lawsuit for $380,000, claiming that the popstar was a nightmare to work for and regularily made diva-like demands.

O’Neill alleged that for $75,000-a-year she had to cater to Gaga’s every whim at any hour of the day or night. According to court papers obtained by The New York Post, O’Neill was responsible for “ensuring the promptness of a towel following a shower and serving as a personal alarm clock to keep [Gaga] on schedule.”

Meanwhile, Gaga is currently preparing to reveal the name of her forthcoming album.
