The American singer and Australian billionaire, who were engaged from January to October 2016, entered into a settlement agreement a few months ago.
Carey was initially seeking a settlement deal worth a jaw-dropping $50 million, but their eventual agreement was reportedly worth considerably less than that.
It was claimed her overall settlement package is valued between $5 and $10 million.
It is also reported that the blonde beauty is keeping the large diamond engagement ring he gave her. Carey has continued to wear her engagement ring over recent months, even after the final terms were agreed on. The engagement is rumoured to be worth $10 million.
Carey is believed to have received such a large settlement due to the fact she moved to Los Angeles to be with the businessman.
Since her split from Packer, Mariah has been spending time with dancer Bryan Tanaka, 34.
