Celeste Barber has responded to critics after she was widely slammed for her appearance on the cover of the upcoming September issue of Marie Claire. 

The comedian, 43, who is best known for poking fun at overproduced photos and videos often posted by beautiful models, has been accused of  becoming 'what she mocked' by posing for the 'heavily photoshopped' cover shoot on her feed.  

However on Thursday, Celeste defiantly returned to Instagram to push back at her naysayers - insisting that her image wasn't photoshopped. 

'Hi, I need to tell you all something about this photo shoot, and it's going to piss some of you off. It's not photoshopped! I just look that f**king good! I know!' Celeste said. 

'You guys are so used to me showing you what I look like as a slapped arse. This is me as well! Guys, I just look this good,' she continued.    

Celeste went on to praise the creative team for transforming her into a cover girl. 

'It's hard - I just look this good when there's 15 kilos of hair put on my head and then Koh [hairstylist] has to snatch my face up to give me a bit of a Kris Jenner lift to hold the wig in place,' she said. 

She went on to praise her makeup artist who painted her face 'like an absolute wizard,' adding: 'I have a feeling, I think they actually shipped lighting in for this, because sister needs a bit of help.' 

Celeste then credited her photographer for his 'amazing angles with the camera', before reiterating: 'This is just how I look. I'm so sorry, but I look f**king great.' 

The cover, which she shared to Instagram on Wednesday, saw Celeste attempting to stay true to her roots as she parodied singer Jennifer Lopez's infamous 2000 Grammys green dress.

However, some followers were left outraged to see how much Photoshop was used to give Celeste a flawless, almost unrecognisable visage in the image.  

'How can you allow so much Photoshop when all you sell is authenticity?' one person wrote to the comedian.

'So photoshopped. What's a shame,' another added, as a third penned: 'Ah the irony.'

'Did they not know you were beautiful before? Isn't the whole point of the entire bit that you laugh in the face of the celebrity airbrush culture?' said someone else.

'And she became what she mocked,' one user commented. 

Others decided to turn the blame on Marie Claire.

'The amount of editing your photography team has done to Celeste goes against everything she stands for,' one outraged follower said.

'Heavily photoshopped Celeste Barber is sacrilege,' another agreed.

 Someone else stood up for Celeste, saying the media personality had every right to pose for a glamour shoot because she was 'making an impact' on the world.

'To connect with the regular normal day to day person is her shtick,' they added.

'If you don't understand that and solely judge from this picture then you don't know anything about her nor Marie Claire nor what it is to be a woman standing for other women!'  

Celeste is known for mocking models and celebrities for their over-the-top glamour shots and saucy videos flaunting their trim figures.

In April, she left locals appalled with her latest stunt in Paris when she strolled the streets of the French capital in nothing but her undies. 

In footage shared to Instagram, she pranced around in her skimpy smalls sipping a coffee, mocking similar footage filmed by a young model in Italy.

However, onlookers appeared less thrilled at her brazen display, with some pointing in disgust at her wild sideshow.

The social media star captioned the footage with some amusing words. 

'It's important to blend in when travelling,' she wrote.
