If your kids are big fans of The Wiggles, and you find yourself watching hours of re-runs on the weekends or schlepping your whole family off to the group's live shows, you might have found yourself pondering some deep thoughts about Emma 'Wiggle' Watkins' glorious red hair.
Fans of the popular children's entertainment group have been pestering the much-loved Yellow Wiggle for years about whether her famous pigtails are real or not.
And now the 30-year-old has revealed the truth about her hair in a new viral YouTube video, filmed for US beauty website Allure.
"I'm about to confirm that I do wear a wig in The Wiggles show," Emma explained in a video titled The Wiggles' Emma Watkins' Entire Routine, from Waking Up to Showtime, which has been viewed more than 1.4 million times online.
"There's been lots of chat on all different forums about whether it's my real hair or not. Initially at the beginning, I was using my own hair and that's why it was quite confusing, especially when people were watching the first Wiggly series compared to the second Wiggly series. In this one I didn't have a wig and that one I did.
"So yes, I do wear a wig. And I don't just have one, I've got about four wigs now. Some for touring, some for filming overseas and one that I've got at home all the time, just in case."
Emma's hair is naturally super curly, but a twist of fate early on during her first experience with The Wiggles 10 years ago would set in stone the hairstyle she has now.
"When we found out we were becoming Wiggles, I was getting my hair dyed. We got a phone call saying you need to come back for prep. We didn't have any time to let my hair dry naturally, so she [Emma's hairdresser] blow-dried my hair, so when I came back for all my press photos, my hair looked like this and so I had to continue making my hair look like this," Emma explained to Allure.
"But after about a year and a half, my hair started to fall out because I was parting it in the same place everyday, and that's why I invested in a good wig. It's so much easier to do a wig and it gives a sense of consistency to the character Emma Wiggle."
Emma, who is a natural blonde, gets her own hair dyed red at the same time her four wigs get their colour refreshed.
She also sleeps on a silk pillowcase and when she travels, each wig is wrapped in a silk scarf, to ensure the hair is kept soft and shiny.
Emma has quickly become one of the most popular Wiggles stars, and alongside the interest in her work is a huge amount of investment in her personal life.
Her current boyfriend is is Oliver Brian, who plays the guitar and banjo for The Wiggles.
In December 2019, Emma revealed the pair were officially an item. She confessed to Stellar magazine that she is indeed "in love" and that the two had worked together and were friends of four years before he asked her out on a dinner date.
"He's very opposite to me," Emma said.
"He's a very calm and thoughtful person and I've always been interested in his mind and his take on life, and his morals. He loves talking about the environment and food production. It's not very 'Wiggly', but it's been nice for me to talk about things not just concerning ourselves, but people everywhere around the world."
Emma also admitted that since she and Oliver started dating, she's learned to relax a bit more and stress less about the little things.
"I'm a bit particular. I used to worry about being late or not getting my pirouette right, but he's taught me not to worry and not to focus on myself, but to help other people. The last couple of months have been really eye-opening. I've relaxed a lot more," she said.

Meanwhile, Emma's ex-husband and Purple Wiggle Lachlan Gillespie is also dating within the Wiggles family, having found love with ballet dancer Dana Stephensen.
But if you thought that would make things awkward between the pair, you're wrong, with Emma insisting there is no bad blood between the exes.
In fact, Emma says she was the first to suggest Lachy and the mother-of-one Dana would be "perfect together."
Emma and Lachy announced that they were divorcing in August 2018 and admitted that they naturally drifted apart during their marriage.
Emma revealed on the ABC's Australian Story program that it was a mutual decision to separate.
"The media does doubt our affection for each other and they won't write about that," Emma said.
"But we genuinely care about each other and we have been through all of this together. Out of everybody, the only person that really gets me is Lachy."
