While Guy Sebastian's career-defining stint on the very first season of Australian Idol in 2003 catapulted him to stardom, the show can take credit for not just the pop star's thriving work life, but also his wonderful family.
That's right - Guy met his wife of 17 years Jules Sebastian on the hit reality show - and now the cute couple have two adorable children together, Hudson and Archer.
The pop singer is back on our screens this week with the premiere of the new season of The Voice, so what better time to take a look at the woman who has stood by Guy's side after all these years.
Guy, 37, revealed he first encountered Jules during auditions for Australian Idol - and the pair had an undeniable connection.
"She can sing, and funnily enough she auditioned with me on Idol all those years ago. She didn't quite make it," he joked on The Project in 2016.
"It's pretty cheesy, we met singing at a wedding together and had to learn this really cheesy love song," Guy revealed.
"We're looking into each other's eyes, singing these lyrics and some sparks flew, and you know we're still together."
The pair got together when they were very young, still teenagers in fact, but still manage to make their relationship work.
"She's a gem and she's my rock," Guy said of his wife.
But like any married couple, things haven't always been smooth sailing.
In fact, the couple actually split before they were married.
Guy revealed Jules dumped him early on in their relationship because he was a "rubbish boyfriend" who acted like a bit of a "douche".
"She left me before. I was a rubbish boyfriend and I was never there ... I was not a gentleman. I didn't believe in opening doors," Guy told Kyle and Jackie O in 2017.
"It took her breaking up with me for me to realise I was being a douche," he explained.
It was during this time that Guy and his fellow coach on The Voice, Delta Goodrem, had a little romance.
Guy revealed that 16 years ago, the pair "kinda hung out ... call it dates or whatever", while he and Jules were on a break.
"To be honest, it was so brief," he told Who, before adding: "We were never girlfriend and boyfriend, we were literally just seeing each other."
Delta however, brushed off the comments, telling the Kyle and Jackie O show: "Oh my God, was he talking about that?"
She then confirmed that one of the so-called dates consisted of the pair simply watching a Harry Potter film together, so not exactly a steamy affair!
They say the couple that shreds together stays together, and that's exactly what Guy and Jules did in 2017, when the Angels Brought Me Here hit-maker decided to undergo a dramatic eight-week health and fitness transformation, to get himself in shape for a Men's Health magazine cover shoot.
Jules decided to get on board as well - and the pair both completely changed their bodies.
They cut out sugar, carbs and alcohol for and also exercised six times a week.
"It was a very busy time for us and I remember being out at a concert, and there was this huge cheese platter and champagne flowing, and Guy and I were just staring at the food holding each other, saying 'don't do it, don't do it!'," Jules told Body & Soul.
They had the help of specialist personal trainers who pushed them to their limits and also gave nutritional advice.
"I love food and I love bad food – hot chips and carbs are my weakness," Jules admitted.
"Each meal time it's a decision for me; 'Am I going to go for the healthy option or am I going to go for the unhealthy option. If I go out for breakfast I weigh up the French toast or pancakes against the avocado smash and poached eggs. It's still delicious, but just not full of sugar and bad stuff."
Now the mother-of-two says she hasn't looked back and tries to make exercise and eating well a part of her everyday life.
"Hand on my heart I can say that it has changed my life. It sounds so dramatic but it really has. More than the body transformation, It's how I feel. I have more energy, I am happier, I'm in a better mood, I'm better for my kids, I'm a better mum, I'm a better wife. My mind is really clear."

And it's clearly paying off, with Guy recently admitting that he thinks his wife is the most beautiful she's ever been.
"I think Jules has gotten hotter, with age. I mean you should've seen her when I first started dating her - not hot. I've told her that," Guy has previously joked.
"We were best mates, we started dating - because we were mates I didn't find her hot and then as the years went on I was like, 'She's really hot'."
We think Jules has always looked stunning - and we're glad Guy has finally realised that too!
