She's the most popular Wiggle and the first female to be welcomed into the iconic children's group. However behind the scenes, Emma Watkins has endured the most "tumultuous" year of her life.
When news broke in August about the breakdown of her marriage to Lachy Gillespie, the Purple Wiggle, a legion of toddlers and parents across the country were devastated.
The couple announced their split after being married just two years.
And now, 28-year-old Watkins and those closest to her, have spoken to ABC's Australian Story about her painful battle with endometriosis and its subsequent impact on her marriage.
While on tour in Canada last year, the Yellow Wiggle was tiring easily and getting very ill.
"I started to feel really tired and rundown," she admitted.
Along with fatigue and cramping in her legs, Watkins said she also experienced a heavier menstrual cycle than usual. Then one day while the group were recording in studio, she collapsed on the floor.
"She was absolutely just in agony and she couldn't get up. She didn't know why," Gillespie recalled. "She just had such strong cramps and couldn't move. So that was really frightening."
Eventually, after ignoring all the signs because she was "too busy", Watkins went to see a specialist. It turned out to be stage 4 endometriosis, the most severe form of the disease.
"Once I'd seen Emma, taken her history and done an ultrasound, it became crystal clear she had endometriosis," explains gynaecologist Professor Jason Abbott. "And she's just been ignoring it and pushing it by the wayside."
"I told her she'd done more for endometriosis in one interview than I'd done in my last 20 years," Professor Abbott said.
While Watkins was back performing with the group six week later, her recovery has been challenging and ongoing.
"She's a real trooper, but I really do worry about her," said Wiggles founder Anthony Field. "I read people saying 'oh, she's fine now', but the reality is not what she presents."
"On the last tour she was on the ground. We were going to call an ambulance, she was in such pain. And that happened maybe two, three times since she's been back."
Watkins also revealed during Australian Story that having endometriosis prompted her to look at other areas of her life and overall wellness.
"I started to feel like the wheels were falling off," she said. "And I couldn't figure out if it was just my health or if it was my relationships."
Watkins says there was a growing awareness between her and Gillespie that "romantically, it just wasn't going the way that our friendship was going".
"I think we decided to part our ways quite organically over the course of about eight months," Watkins says. "It was a mutual decision."
The couple had sold their Sydney apartment in June last year and tried to quietly separate, although the media got wind of the story.
"Being busy has been very helpful and it feels like a bit of a relief now," she said, after the pair decided to release a statement.
"Lachy has been so supportive through all of this and I really can't thank him enough," she said in the interview. "We genuinely care about each other and we have been through all of this together."
"And out of everybody, the only person who really gets me is Lachy."
