She's the self-made Instagram sensation who built an impressive 9.6million follower fanbase.

But fans may have a hard time recognising this popular comedian from her high primary school days.

On Wednesday, the 41-year-old funnywoman in question shared a glimpse into her childhood photo album as she promoted her upcoming comedy tour.

'My tour backup dancer starts this Thursday in LA,' the star, who made her name by parodying celebrities' social media posts, captioned the post.

So can you guess who she is?

The first image captures a very young Celeste dressed in a dance costume. 

The striking outfit featured a white pleated dress, topped with a unique white hat adorned with a voluminous bow, making her look every bit the star she was destined to be. 

The second snapshot showed Celeste donning a snappy ensemble of a black jacket paired with a pink shirt and a stylish yellow tie, topped off with a jaunty hat.

Even at such a tender age, Celeste's penchant for standing out is unmistakably evident in her mischievous smile and spirited pose. 

Celeste has built a loyal fanbase thanks to her Instagram videos and photos spoofing celebrities' lifestyles.

She has previously poked fun at the likes of Tammy Hembrow, Miley Cyrus and Gwyneth Paltrow, by mimicking their posts in her own unique way. 

In March, Celeste appeared on The Project  and revealed that some influencers and celebrities often contact her begging to be parodied.

'Yep. Heaps,' she said when asked if anyone had asked to be featured on her profile.

'I also get people going, "Have you seen so and so? You need to parody her. She needs the followers". It's full on,' she added.  

However, Celeste has also made friends with some big names after mocking them.

'I am friendly with some of them, which is nice,' she said, before joking: 'Anyway, I was talking to Cindy Crawford and she said...'
