“Basketball Wives” star Tami Roman is being sued by her ex-manager … who claims he helped make Tami rich and famous — but she refuses to pay him for a job well done.

Jerry Silverhardt filed the lawsuit Monday in L.A. County Superior Court — claiming he was instrumental in securing Tami’s “Basketball Wives” gig … but instead of being grateful, she fired his ass.

Jerry claims Tami paid him for Season Two — but then left him out to dry after she ended their relationship in February … refusing to pay for work she did on the recently completed Season 3.

According to Jerry, Tami’s oral contract with him is crystal clear … she owes him 10% no matter what on all “Wives” paychecks for seasons 3 through 6 — and she better pay up, stat. Calls to Tami were not returned. TMZ
