Celeste Barber was ruthlessly slammed by fans on Wednesday after she posed for the cover of the upcoming September issue of Marie Claire. 

The comedian, 43, is best known for making hilarious parody videos online, mocking over-produced videos and pictures often posted by beautiful models. 

But now she has been accused of becoming 'what she mocked' after she posed for a 'heavily photoshopped' glamour shoot and shared it to Instagram.

The cover photo 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.

Daily Mail has reached out to Celeste for comment on the Marie Claire cover shoot.
