When asked how long he and Lowe had been dating, Joy responded, "Most of this year actually."
This suggests that the pair may have been an item long before any of us realised!
Although his girlfriend was absent at the AACTA Awards, the singer performed an acoustic version of his single "We're Going Home" for the nominees and audience.
While we had the chance, we also asked the Riptide star about his decision to re-work the single "I'm With You."
"[The single edit] is really different. I really do like the original stripped down version," Joy tells Who.
"I think the idea was to make it a bit more, honestly, to give it a bit of a beat and [make it] a bit more boppy."
"And the radio does play songs that are completely acoustic, [but] very rarely, so it was just like giving it more of a shot on the radio."
We can't wait to see what the artist comes up with next!
