Spinderella goes on to say that she was again promised a third of the royalties from The Salt N Pepa Show which ran in 2007 but she did not receive her share of the money from the reality show.
The 47-year-old claims she received nothing from the group's performance at the 2018 Billboard Music Awards and has heard nothing about a new Lifetime miniseries about the band.
She says the final straw was when Sound Exchange, which handles the distribution of royalties to artists, informed her that Salt-N-Pepa had earned more than $US600,000 over the past 10 years but she was not given any of that money.
Spinderella is also claiming trademark infringements, saying Salt-N-Pepa continue to use her name to promote performances.
Salt-N-Pepa, who formed in 1985, were the first all-female rap ground to go platinum and won Best Rap Performance at the 1995 Grammys.
They had a string of hits including Push It, Shoop, Let's Talk About Sex and Whatta Man.
