Alanis Morissette is suing her former manager Jonathan Schwartz for $4.7 million.

Following their split, the 'Jagged Little Pill' singer hired a new financial manager who investigated her concerns and it is claimed found $4.7 million was missing from her accounts.

According to a report by ET Canada, the findings were presented to GSO and Schwartz who stated the singer had asked him to withdraw the money and invest it into a marijuana business, a claim which she denies.

Alanis threatened to sue GSO but the company are reportedly distancing themselves from the financial manager and even branded him a "disgrace."

The Hollywood Reporter listed Schwartz, 46, as one of 'Hollywood's 25 most powerful business managers' in 2014 and said he was GSO's youngest partner and someone who will "go to extremes" to assist famous clients.

In the piece, the manager also contributed examples of occasions where has been asked to sign off on expenditure for celebrities who lead a lavish lifestyle.

He said: "Biggest check cut: Probably a private plane. For some of these high-profile clients, you're not going to see them walking around LAX."

Meanwhile, 'Ironic' hitmaker Alanis is pregnant with her second child with her husband Mario 'Souleye' Treadway.

The couple already have five-year-old son Ever together.
