Celeste Barber risked baring all in her latest parody video in which she mocked a model who performed a headstand in nothing but a pair of bikini bottoms.

The comedian, 40, posted a clip of the woman showing off her incredible figure and flexibility as she performed the splits in a headstand position wearing a G-string.

It then cut to footage of Celeste attempting the same stunt in her own bikini bottoms, but failing to get her legs over her head.

A man's voice could be heard saying in the background of the model's video: 'I am beautiful. I am loved. I am safe. I am free. I don't need to be like them. I just need to be like me.'

But in Celeste's version, the voice says: 'I'm hungry. I'm tired. I've got a cramp. I just farted. My hips are out of whack. I hope you're all enjoying my crack.'

It comes after Celeste recently attracted the attention of actress Jessica Alba.

She won praise from the movie star after parodying one of her videos. 

The funnywoman shared a clip of Jessica, 41, doing her wellness routine in an airplane bathroom while on a flight to London.

In the original clip, the wellness guru removes her makeup before adding a cleanser and moisturiser with products from her brand Honest Beauty.

'No shame in my game,' she wrote in the caption showing off her fresh-faced look.

In the parody, Celeste also takes her makeup off, before wiping under her arms, flossing and spraying herself with body spray.

She then fumbles around, applying more makeup before shouting 'I'm in here!' when someone knocks on the door.

'Staying hydrated and fresh-faced while on the road has kept me sane,' she joked in the caption.

The video won praise from many fans, who branded it 'hilarious' and 'relatable', while Jessica commented on the clip: 'I love you @celestebarber - you are epic.'

The Aussie comedian became a global star thanks to her hilarious parodies in which she mocks celebrities and influencers.
