The eye-popping amount is actually relatively reasonable compared to others, Erika insisted in an interview with E! News.
'There are many people that spend a lot more. So 40 is actually kind of on the low, when you really start getting into what's done,' she said.
Photos of Erika's beauty evolution over the last 10 years speak for themselves, with the singer appearing noticeably more glammed up over the years.
The beauty transformation was evident as early as 2010, when Erika appeared on the red carpet with glossy lips and loose waves.
Erika's metamorphosis was also noticeable in 2012, the year she underwent her nose job.
The star was pictured with a noticeably slimmer nose while on the red carpet.
Little of Erika's appearance has changed in recent years, however, with the star embracing her super glam look and head full of bright blonde hair.
A star on The Real Housewives Of Beverly Hills, Erika has been making headlines lately for her divorce from husband Tom and his embezzlement scandal.
Erika, who was married to Tom for 21 years and did not have a prenup with him, filed for divorce last year.
Jayne and Girardi have since been accused of embezzling millions of dollars meant for families who lost loved ones in the 2018 Lion Air plane crash in a lawsuit.
The lawsuit also claimed their divorce was a 'sham' in order to protect his money from debt collectors.
Sources close to Erika told TMZ last month that she insisted she had 'zero clue' what the 82-year-old Girardi was doing with his or her money and that all money she had earned went straight to him or his law firm, Girardi & Keese.
In September, Jayne was 'ordered to turn over financial records' from her accountant, lawyer and landlord in embezzlement lawsuit with Girardi.
The order comes as a bankruptcy trustee continues to investigate Girardi's assets, amid claims that both Girardi and Jayne allegedly embezzled settlement funds that were meant to help the families of plane crash victims on Lion Air Flight 610.
However, according to legal documents obtained by People magazine, Jayne's lawyers were already maintaining that the reality star 'has been and remains willing to cooperate fully with the Trustee's investigation in this bankruptcy of debtor Girardi & Keese.'
While Erika maintained that she was 'kept away from the books,' the trustee in a new lawsuit is mandating that even if that were to be the case 'it would be a miscarriage of justice if [she] was allowed to simply walk completely free of owing over $25,000,000 to the Estate.'
