Alanis Morissette: Business Manager Allegedly Screwed Her Out of Millions

EXCLUSIVE

Alanis Morissette was fleeced to the tune of $4.7 million by her famous business manager ... so claims the company where the manager worked, claiming he used the money to fund a lavish and glitzy lifestyle.

GSO Business Management claims Jonathan Schwartz, one of its business managers, took on Alanis as a client, in addition to other famous entertainers including Beyonce and Mariah Carey. According to the lawsuit, Alanis dumped Schwartz in 2016 and hired a new manager, who began investigating where her money went.

The suit claims $4.7 million could not be accounted for, and GSO confronted Schwartz, who told this story ... Alanis told him to withdraw the money so she could invest in a marijuana growing business and he obliged by giving the money to her reps. GSO says his story didn't check out. The suit says Alanis vehemently denies she ever asked Schwartz to invest in the pot biz.

The suit claims Schwartz stole the money to support an opulent lifestyle, including a $50,000 vacation to Bora Bora and paying off a $75,000 gambling debt at a casino in the Bahamas.

The lawsuit doesn't mention Alanis by name -- it just refers to a "former client" -- but sources connected with the singer tell us she's the victim.

According to the suit, Alanis threatened to sue GSO and it wants Schwartz to pay any judgment. Since he was a partner the firm needs a court order, which it is seeking, to kick him out of the firm.

The firm insists Schwartz was acting on his own and was a "disgrace." GSO says Schwartz went rogue and acted on his own, without the firm's knowledge or consent.
