And even Stella herself had a warning for the diva that she relayed to the publication: ‘The truth will be revealed. It’ll come out in court.’

An insider added, ‘Stella will go on the record about her time with Mariah and what it’s really like working with her. Stella will not ‘hold back.

‘There will be no shortage of stories. Mariah should be scared.’

Among the things that Stella, 45, could talk about – according to a source at the publication – is Mariah’s love life (she is now dating dancer Bryan Tanaka, 35) and ‘yo-yo dieting.’

Mariah and her new managers at Roc Nation have said that Carey owes Bulochnikov no money.

But Stella is not backing down.

Stella plans to sue for breach of contract because she was let go before her contract expired, she claims.

The manager worked with Mariah for three years and oversaw her disastrous reality TV show.

Carey denied the claims.

In April Stella said she was suing for several things, including sexual harassment.

Bulochnikov filed a summons in New York stating that she plans to sue Carey for allegedly violating the U.S. Civil Rights Act and the Fair Employment and Housing Act.

And she included her breach of contract at the time.

And according to TMZ Stella is the victim of ‘sexual harassment,’ because ‘the star was often nude in front of her.’

Bulochnikov is reportedly seeking damages and interest.

A rep for Carey told Page Six in April, ‘Stella Bulochnikov was terminated from employment as Mariah¹s manager due to failure to perform her job effectively and ill-serving her client.

‘Stella was not under contract for employment. She has been spreading false rumors to any media outlet that will publish them.

‘We won’t respond to lies and threats. Again, if this frivolous and baseless claim is filed, we will defend against it vigorously and successfully. It is also interesting to note that this is the first lawyer who will move forward on Stella’s behalf, having previously gone through three others who wouldn’t.’

‘This is me at this moment in my life being able to express myself as a writer and a singer. I’m just really in a good place.’

And she said she’s doing it her way.

‘My fans just want to hear me express myself and speak from the heart and sing from the heart,’ says Carey.

‘Some of the record is lighthearted and fun, and some [songs] I really went deep in terms of the lyrical content. There’s a nice cross-section of things.’

She has also revealed she is extending her The Butterfly Returns Las Vegas residency at Caesars Palace into 2019 with new dates in February .
