Marloes Stevens: 2020-now
Cody’s current squeeze, model Marloes Stevens, has been dating the blond since December 2020. And, according to insiders, there was chemistry between the pair from the get-go.
“There was this instant spark when they first met and a lot of times that fades away after a few dates, but the connection just kept growing stronger,” a source told Hollywood Life.
“Cody and Marloes have grown really comfortable with each other. Marloes has always been playful and she loves that Cody just gets her. He lets her be herself so she can be goofy and joke around.”
Miley Cyrus: 2019 -2020
Following the bombshell that Miley Cyrus and Liam Hemsworth were divorcing after a year of marriage and a decade of being on-again, off-again, the world was whipped into a further frenzy when longtime pals Miley and Cody began dating.
Not ones to shy away from the public, Miley and Cody posted many sizzling couple selfies during their time together before it all fell apart as they vowed to "work on themselves".
Ali Lohan: 2018
While not much is publicly known about the ins and outs of Ali Lohan and Cody Simpson's romance, some rare details were spilled from an surprising source in a very unexpected way.
Back in 2019, Ali's sister Lindsay Lohan was working as a judge on The Masked Singer Australia, which just so happened to be the season that Cody won while performing as The Robot.
Guessing it was her sibling's ex behind the costume, The Parent Trap star declared: "If it is you, we have a lot to talk about, and this is not the arena for it."
She added: "I want my furniture back, because I bought your furniture for your house in Venice."
Later explaining what she meant by the comments, Lindsay revealed that while Ali was dating Cody, he was living in a "beach shack" with no proper bed (which Ali was not a fan of) so Lindsay bought him a bed. The more you know!
Clair Wuestenberg: 2018
Back in 2018, Cody struck up a short-lived romance with model Clair Wuestenberg. But unlike some of his exes, which he was able to remain amicable with, this was one relationship which went down in flames.
Following their acrimonious split, Clair took to Instagram to blast Cody as a "narcissistic conman" and revealed she was deeply unhappy with the way he called it quits.
“The more I’ve been talking to people, the more I can step back and see myself for who I am rather than identifying with the relationship I’ve been in,” she said.
“I guess I should address the situation so people know what I’m talking about. My boyfriend broke up with me, and in a really, really sh***y way. I’d like to tell everybody about it, but I’m sure it would be not so good for his career, so I’ll keep it quiet.”
Charlotte Lawrence: 2016
Look, it appears Cody may just have a type (and is he taking cues from Leonardo DiCaprio?). Charlotte Lawrence is another model (and singer!), who Cody dated back in 2016. They were spotted together at the beach that year, sparking romance rumours.
Sierra Swartz: 2016
Gold Coast native Cody had eyes for yet another model in 2016, this time a stunning blonde named Sierra Swartz. They were photographed locking lips while having breakfast in Los Angeles.
Sahara Ray: 2015
Cody has often been dubbed "Australia's answer to Justin Bieber" and it seems the pair have another thing in common other than their singing talents: their taste in women.
In 2015, Cody was linked to Sahara Ray who has also been embroiled in a romance with the Biebs in the past.
Gigi Hadid: 2013 -2015
During their two-year relationship Cody and Victoria's Secret model Gigi Hadid appeared rock solid. However, the high-profile nature of the romance became taxing and they eventually went their separate ways.
“It was a super-cool experience, having a first love like that,” he told GQ Australia later.
“Then people started paying way more attention to us, which took its toll because I didn’t want to be a celebrity — just some guy who’s dating models. It started getting super gnarly where we couldn’t go out to restaurants. I got scared. Then I had to go away on tour, and we ended up splitting up.”

Kylie Jenner: 2011
If fate had taken a different turn, Cody could have joined Kanye and Scott Disick as some of the men associated with the most famous family in the States. But alas, Cody's short-lived affair with Kylie Jenner in 2011 was not to be.
"The whole K-O-D-Y thing didn't really work out for me," Cody later joked about the situation, referencing the Kardashians' names all beginning with the letter "K".
Bella Thorne: 2011
Teen dreams seemingly became reality in 2011 when rumours ran rampant that Cody and Disney star Bella Thorne had gotten together following a flirty Twitter exchange. But were they ever official? Or were they just close friends? We may never know, but they sure looked cute together.
Stella Hudgens: 2011
Way back in 2011, Cody was also linked to Vanessa Hudgens' younger sister Stella after the teens hung out together. Neither has ever confirmed whether or not they were hooking up, so a question mark still lingers over whether they were together or just mates.

Joanne Herarghty: 2008-2010
There's not much info or images of Cody's ex Joanne Herarghty hanging around on the internet as their romance kicked off before he hit the big time. However, given the length of their relationship, she still deserves an honoury mention on the list.
