14 years on from hisIdoldebut, here's a look at what Dean has been up to.

His beginings on Australian Idol.

We first met Dean on season four ofAustralian Idolin 2006. The young singer auditioned in his hometown of Melbourne and went on to impress the judges (and the rest of Australia) with his self-composed song 'Nice to Meet You'.

Alas, the then 20-year-old ended up placing third in the compeitition behind winner Damien Leith and runner-up Jessica Mauboy.

But while he may not have taken home the win, Dean was thrust into the spotlight and his debut albumRushended up making it to top seven on the ARIA charts the following year.

"I had such a great run, I was blessed to do so well on Australian Idol even though I was not one of the best vocalists on the show for sure," he told The Morning Show last week.

His acting career on Neighbours and Glee.

AfterAustralian Idol, Dean tried his hand at acting when he was offered a role on TV soap opera,Neighbours.

It was a career move that he wasn't expecting.

"After Australian Idol I still had a huge passion to become a pop star. Acting came out of nowhere for me,” he told The Advertiser in 2012.

"Neighbours offered me a one-year deal and I really have them to thank. That was where I learnt everything I've based my acting career on."

From 2008, Dean played Ty Harper onNeighbours,reinforcing his status as Australia's teen hearthrob.

"I was fairly happy with how Ty turned out, I really enjoyed playing Ty, but I needed a lifestyle change," he told news.com.au.

As a committed Chrisitan, Dean said the he struggled with some of his character's storylines.

"In some instances my personal beliefs maybe were contradicting with what the character was doing," he told the publicaiton.

"I am not saying I was forced to do anything, but looking at the character I don't necessarily agree with everything he did."

AfterNeighbours,the singer-turned-actor went on to appear in Steven Spielberg's TV seriesTerra Novain 2011.

A year later he scored his big break in Hollywood when he landed the role of Brody Weston on hit TV seriesGlee.

"WOW!! I feel absolutely speechless, and so honoured to be joining the undeniably talented team of @GLEEonFOX!!" the then 26-year-old tweeted at the time.

"I'm very excited for the journey, and I'm warming my voice up as we speak."

But before playing Lea Michelle’s love interest on the show, Dean had to go through rigours audition process.

"For me, this role seems like it was one of the most sought after this year. You're never sure which pilots are going to go to air, so to score a role on a show that's had such a successful few seasons is incredible for me,” he told Teen Vogue.

The 34-year-old recently defended Lea when she was accused of bullying otherGleecast members.

Speaking to the Daily Mail last month, Dean explained that the actress was very welcoming when he joined the show.

"When jumping onto a hugely successful and established show like Glee, I went into it expecting to be known as the 'new guy' for at least a month, but that wasn't the case at all. I almost immediately felt welcomed, and to be totally honest, out of everyone, Lea was the most friendly to me," he told the publicaiton.

Dean also paid tribute to the lateGleeactress Naya Rivera after her body was discovered in in California's Lake Piru earlier this month.

"Naya was an unbelievably talented performer who I got the pleasure of working with. The only thing that rivalled her acting abilities was her incredible voice," he toldThe Daily Telegraph.

"I am extremely saddened to hear that we have lost someone who had such a positive impact on so many people's lives through her art."

In an interview with Today Extra, Dean explained that his last days filming the show were spent with the Naya.

"What is crazy is one of my last two scenes [on Glee] was shot with her [Naya] and Cory, which is nuts because on the anniversary of his death they found her at the lake," he said.

A brief engagment to one of The Veronicas.

Back in 2008, Dean was briefly engaged to The Veronicas singer Lisa Origliasso. And by 'brief' we mean, for three months.

While the relationship didn't end up working out, the expereince taught Dean a few things about himself.

"It was a good turning point for me, because I think I was still very young and ignorant. At that point in my life, I was being caught up in the success of Idol and what was going on with my music, just touring around and just having fun, fun, fun," he told //news.com news.com.au.

"I don't think I paid attention to the enormity of the commitment [that] getting engaged [is] and the situation.

"It taught me to think about things in a lot more depth. Not that I regret it. Everything happens for a reason."

Three years later, Dean met his now wife and Amercian actress Jillian Murray on the set of the 2011 filmNever Back Down 2.

"I'm so glad I did that movie, for sure," he told the publicaiton.

The pair later tied the knot in 2017 in front of 75 of their closest friends and family at Santa Ynez Valley.
