Lady Gaga in Beverly Hills
MGA claims Gaga acted in "bad faith" after initially agreeing to include a voice chip with the doll and have it ready for sale by Christmas.
Now, the company believes, Gaga is attempting to delay the item's release to coincide with her new album in 2013.
In its Manhattan Supreme Court suit, MGA asserts that Gaga and her team “engaged in intentional and deliberate delays” to prevent it from meeting its summer deadline with distributors.
Lady Gaga has not seen the court documents, her spokesperson tells The New York Daily News, but is "confident she will prevail."
