With her siren-red hair and oversized bow Emma Watkins, aka the yellow Wiggle, is one of the most recognisable faces on television to little people and parents alike.
But this week, the children's entertainer has left fans stunned by revealing she has a sister who looks just like her.
On Tuesday the 31-year-old, who made history when she joined The Wiggles as the first female member in 2012, took to Instagram to share a candid snap with her lookalike sister, Hayley Watkins.
In the stunning snap, the siblings share a laugh as they dance in a garden.
Emma simply captioned the shot with the hashtag "sisters." It marks the first time Hayley has made an appearance on her famous sister's Instagram page.
Fans were quick to remark on the pair's likeness.
"Ahh they look so alike. I had no idea she had a sister," one person noted.
Another agreed: "😍 she looks just like Emma but blonde! 💁🏼♀️"
"Cutest sisters ever ❤️🙌," a third mused.
In fact, it turns out Emma is a natural blonde like Hayley but dyes her hair red and wears a red wig for her role in the children's supergroup.
According to Hayley's bio, she is a model, actress and dancer and has landed extra work in shows like Underbelly, Home And Away and... wait for it! Yep, you guessed it - The Wiggles.
That's right, in 2017 she landed the role as a princess in the Wiggle Town TV series alongside her famous sister.
"I am strong character actress with an extensive background in modelling," Hayley explains on her website.

"Based in Sydney, Australia I am professionally trained in modelling, acting & dance. I tend to project a strong Australian outdoor image complimented by unique European roots. My athletic figure is a direct result of my love for sport and physical activity," she adds.
"I have a huge passion for tropical travel & exploring the natural elements with a deep fascination for the ocean which inspires & motivates me."
It's clear Hayley is just as talented as her famous sister and we can't wait to see what she does next.
