The singing sensation had been dating his girlfriend since last year, but it appears their romance is now no more.
When asked if he was single during a radio appearance on The Kyle and Jackie O show recently, Ed replied: "Yes."
Following his revelation, Jackie O told her co-star Kyle: "He looks like he's about to start crying - you shouldn't have asked that."
And clearly surprised to be questioned about his relationship status live on air, Ed added: "'Erm… well that's interesting, that's the first time I've spoken about that... I didn't know you were going to ask."
Keeping any reasons behind their break-up close to his chest, Ed didn't divulge anymore information.
That's not surprising though, as the 24-year-old had always been quite private when it came to his romance.
He first spoke about Athina in May last year, only sharing that his other half was Greek, works for a chef and is "really cool".
While he wasn't one to publicise their relationship on social media, Athina did, however, share multiple pictures of the pair on Instagram - including one of the pair in sumo suits on Ed's birthday last month.
Ed's revelation that he and Athina have decided to go their separate ways comes as he is busy touring in Australia.
As well as taking to the stage, the songwriter has also been trying his hand at a spot of TV work.
Ed is set to star in an upcoming episode of Australian soap Home and Away!
The soap's Facebook account revealed: "He will appear as himself in the series, but storyline details about what brings Ed to Summer Bay are being kept under wraps for now."
