Toy firm claims pop star acted in "bad faith" by delaying product.
MGA has allegedly filed a $10 million lawsuit against Lady Gaga, her management firm, and Universal Music Group's licensing and merchandising company Bravado International.
Toy company MGA Entertainment supposedly accused Gaga of making last-minute requests to remove a voice chip from its Lady Gaga doll, which would delay the product's launch beyond Christmas.
MGA paid $1 million for the licensing rights to make the doll. Now it is seeking damages and the permission to distribute the doll as it stands.
