Guy Sebastian and his wife Jules have been together for almost two decades after tying the knot back in 2008. The couple have two kids, Hudson,8, and Archer, 5.

In order to kill time during self-isolation, the couple reflected on their relationship and answered questions from fans on Instagram Live.

Guy revealed that he popped the question while on a trip to Queensland’s Hervey Bay, where he had bought an investment property.

"I was pretending that we were holidaying there, and I said let's go for a walk down the beach. There's a nice stretch of beach that's not very populated so I thought it'd be nice and quiet," he said.

"We got to like where this house that I had bought and there's a bench that overlooks the water and we sat on that bench and I got on my knee."

Guy said the nerves almost got the best of him during the proposal and he hadn’t come prepared with a speech.

"I did it really fast because I was really nervous. I didn't even have a speech, I wasn't like 'We've been together for this long...'" he said.

Jules added, "It was literally like we sat down and as soon as his butt hit the bench, he was on the ground with the ring."

Guy had another surprise for his future wife in the investment property, where a bunch of their friends were waiting to celebrate with them.

"It was good. It was really, really good. I couldn't believe it," Jules admitted, before laughing, "Then he said, 'Ok I'm going fishing now' and disappeared for five whole hours."

Jules shared more insight into her marriage is like to Now To Love.

"I think it comes down to I really like Guy. I mean, of course I love him, but I like him, I have a lot of respect for him, I just think he's a really solid dude," Jules said.

"He really makes good decisions, he's really kind to people and he works really hard and he has all those really strong characteristics that I find attractive. It can't all be rainbows and unicorns everyday. Life is just not like that, but yeah, we have a good time.

"We've got to work at it, absolutely - but for the most part, it's been pretty smooth sailing."
