Lady Goo Goo won't be the last of Lady Gaga's legal adversaries.

According to LA Weekly, the Los Angeles-based pop duo Purple Crush are suing Gaga producer Rob Fusari, claiming he owes them money for production work towards the album "Born This Way."

Although none of their work made it to the final record, Isla Cheadle and Jared Selter reportedly claim they labored through hundreds of studio hours for Fusari and his clients without compensation. According to Purple Crush, their role involved expanding upon song snippets Fusari sent them, before forwarding their work along to artists, such as Gaga, who would add lyrics and melody. Work was done in their L.A. and Brooklyn studios.

Purple Crush claim songwriting work for other Fusari clients such as Macy Gray, Little Boots and Greyson Chance.

Additionally, the songwriters claim Fusari had promised to obtain a record deal for them, which he never did.

"It became this struggle between us as artists and us as employees," Cheadle told LA Weekly. "Getting us a record deal became this carrot he dangled in front of us."

Last April, Purple Crush offered Fusari a $10,000 settlement, which he refused. When Fusari countered with a $15,500 lawsuit, the duo announced plans to countersue. So far, no official court dates have been announced, as Purple Crush has been unable to find a lawyer.

Aside from dating Stefani Germanotta and coming up with her now-famous stage name, Fusari co-wrote some of her biggest hits, such as "Paparazzi." Last September, the two settled their own legal disagreements by mutually dropping conflicting lawsuits over, once again, song credits and royalties.
