Salt-N-Pepa's Former DJ Spinderella Is Suing...

Salt-N-Pepa's DJ Spinderella is spinning a lawsuit at the hip-hop duo.

Spinderella claims the group promised her 1/3 of the royalties for their 1999 "Best Of" album which equals to $125k...that she never got.

According to the lawsuit, she also says the groupmates had been paid more than $600k in royalties which she also never saw a dime of.

After being together for nearly 35 years, Spinderella is pushing it...in the lawsuit for trademark infringement, fraud, and breach of contract.
