Grey's Anatomy star Justin Chambers has been playing the part of Dr. Alex Karev in the hit U.S medical drama since 2004, so it's not surprising that he feels like "an old TV actor."

Speaking about working on the same show for over ten years, Justin told RTÉ Ten: "I feel like an old TV actor. It's been a great ride. It's wild how quickly it's gone, but at the same time, I don’t really remember life before this show. It seems like this is what I've always done."

He added: "Not many people can say in today's world that they have been part of television history for over ten seasons. I'm still excited to be there. I'm still excited to work with the people I work with. Hopefully, I will give people a good hour of TV for the next season or two."

After a decade of playing the part of hunky doctor Alex, Justin admits that sometimes he finds it difficult in audition situations to play a different character.

Justin further stated: "Yeah, I'm a bit like Alex and he's a bit like me, but the way we go about our world's are different. I actually had an audition a while ago, and it felt like I was Alex trying to audition for the role and not Justin. You do wear it as a glove.

"The whole character thing is questionable to me. In the end it's all coming from you and your personality,"

The last season of Grey's Anatomy saw Alex striking up a romance with Jo (Camilla Luddington), and RTÉ Ten were eager to find out if their romance will continue to blossom in the upcoming series.

When asked about Alex's love-life, Justin said: "If anything, their relationship is going to blossom. This past year we've seen how they've worked off, off each other. In their relationship, you finally have a character that is similar to Alex – who's come from a broken home, a person who has had to work through a lot of obstacles to become a doctor.

"They complement each other. They're going to explore more of that. Jo being there to help him with his father, to push him and sort of make amends with him, that's just setting an example of what's to come in the future. Now that they live together, it will explore what it's like for him to be domestic and who knows; maybe they'll get married and have kids. Anything is possible."
