The “Bad Romance” hitmaker and her management and licensing companies are being sued for $10 mn by executives at Mga Entertainment for an alleged breach of contract, reports contactmusic.com.

It is claimed Gaga requested the removal of a voice sound chip from the doll which put the company under pressure to meet their deadline for retailers.

Company bosses allege the singer and her team “engaged in intentional and deliberate delays” to stop the toy reaching shelves until 2013, so it coincides with the release of her new album and perfume.
