Cody Simpson is a big fan of taking the high road.

Now that model Gigi Hadid has found (a very public) romance with Zayn Malik, Cody is bombarded by images of his ex-girlfriend falling in love with someone else.

But that doesn't stop the Australian singer from wishing her all the best.

"It's just kind of the natural way things go. You're going to expect that kind of stuff," the "La Da Dee" singer told ET on the red carpet at the iHeartRadio Music Awards in Los Angeles, California, on Sunday, April 3.

"I've kind of been going a different way, taking a little time for myself just hanging out and keeping it low key, and working on my music.

After dating on and off for two years, Cody and Gigi finally ended their teenage love in May 2015. After a brief stint with pop star Joe Jonas, Gigi has confirmed her relationship with former One Direction singer Zayn Malik.

"But I'm always very happy for her and her career and that type of stuff," Cody told ET. "I know how hard she's always worked to kind of get to the point in the modeling industry that she's at now, and I couldn't be more proud of her. We still talk every now and then. It's nice."

Cody has mostly been focused on making the world a better place with his songs. He's was inspired to speak out following the terrorist attacks in Brussels, "I just woke up and I was like, I shed a little tear in bed and everything," Simpson said. "It was strange, it was just a little shocking, you know? All those types of tragedies have been happening around the world these days."

He wrote a song called "I'd Rather Die" in response. He says it's his was of expressing his desire for everyone to live freely and without the "overhanging fear of war."

You see? Cody is clearly too focused on important issues to sit around worrying about what his ex is doing.

Back when Cody was with Gigi, he spoke to People about their relationship, which was based in friendship. "It's give and take - you've got to have a certain trust", he says. "You build something, and for us it's been sustainable. [We're] very supportive of each other, she's stoked for me and it's mutual."

Sounds like a man that's true to his word.
