The insider also claims 67-year-old Olivia 'is desperately worried' for her daughter's obsession with body image.

While US surgeon Dr Tahl N. Humes told New Idea he suspects Chloe has had several breast augmentations and perhaps liposuction, a 'family insider' told the publication that 'some friends are whispering she got a rib removed'. 

New Idea has reported her suspected surgery would have cost approximately $415,000, with alleged bottom surgery and maintenance the most costly, worth a hefty $66,000.

The aspiring singer’s dramatic transformation over the years has prompted many on social media to claim the songwriter has undergone breast enlargement surgery and Botox.

Chloe has previously explained that while she did dabble with fillers in the past, her recently plumped pout is in fact due to a do-it-at-home product that uses a suction technique to help the lips swell up.

'Used my @fullipsenhancer today right before a shoot! Lovin my pout!' Chloe captioned the snap of herself staring into the camera last year.

In a previous post the blonde explained that while her lips are already large as a result of getting lip fillers 'years ago', she still enjoys creating an even more dramatic effect.

'OK I know I already have big lips. I got injections years ago and they just stayed big lol!' she says.

Chloe also recently revealed she has tried the popular waist training trend as well as being a fan of celebrity trainer Tracy Anderson.

A natural brunette, Chloe has indeed undergone a dramatic transformation in the years since she recorded her first tracks as a fresh faced 15-year-old.

However, the model has never spoken about undergoing surgery.

A now-recovering Chloe has battled a slew of health problems in the past after seeking treatment for eating disorders and substance addiction.

In 2013, the Los Angeles-based star spent seven months in a rehabilitation facility to help her combat her cocaine and alcohol abuse.

How she looks now: The aspiring singer, is more than happy to put her assets on display on social media - such as in this post from last year

Anxiety is one of the biggest factors she blames for sending her life into a self-destructive spiral, which she told Daily Mail began with anorexia and ended with cocaine, vodka and antidepressant abuse.

'I had blackouts', she said following her stint in rehab. 

She continued: 'Later, being drunk and high became so routine that I would be high in front of my mum – and I don't think she even noticed because it was such a normal state for me to be in.'

Focusing more on her love of music, Chloe and her actor mother released a revamped version of You Have To Believe last year, which is a dance remix of 1980 hit Magic produced by DJ Dave Aude.
