NEW YORK -- Grammy winner Ne-Yo wants $8 million from his ex-manager.
The Daily News reports that the R&B singer-songwriter has sued one-time manager and confidant Kevin Foster in Manhattan federal court.
Foster started handling Ne-Yo's finances in 2005.
The lawsuit says Foster moved some of Ne-Yo's money without permission. It also alleges that Foster faked Ne-Yo's name on loan documents and invested Ne-Yo's money in a water company that was teetering on the edge of bankruptcy.
The lawsuit seeks $4.5 million plus $3.5 million in fees that Ne-Yo, 34, says he paid Foster.
The Daily News says a phone number for Foster's firm was out of service.
Ne-Yo's real name is Shaffer Smith. His representative didn't return an email seeking comment Thursday.
Ne-Yo has written hits for Beyonce and Rihanna.
