In a chat with Stellar Magazine in May 2020, Delta spoke candidly about her relationship and how they spent time together during lockdown.
“I am pretty consistent with saying to people that my private life is my private life, but we are spending isolation together and, in our household, we’re both performers," Delta explained.
"It’s a relationship of respect. Matt is an incredible musician and we really enjoy working together. Music is how we met, it’s what we both do, so it’s really about just being creative in the household.”
Delta, who was just 15 when her career kicked off, also told the publication that though she knows public interest in her personal life comes with the job, she decided years ago that she wouldn't let anyone's thoughts about her romantic life define her.
“It’s also about me understanding who I was, without other people telling me who I was,” she says.
When the world went into lockdown due to the coronavirus pandemic, Delta and Matthew didn't let that stop their love of music.
The couple hosted The Bunkerdown Sessions on Instagram and for 25 weeks from April through to October, they hosted a series of free online performances featuring brand new songs.
Matthew has also co-produced and co-written several of Delta's recent hits including Solid Gold, Let It Rain and Keep Climbing.
"Very proud to see this out in the world, and very thankful for @deltagoodrem including me in this incredible journey!" Matthew wrote in May 2020 when Keep Climbing was released.
"This song is really special and Delta sounds stunning on it!"
Though we don't know much more about Matthew, Delta told WHO this year what she finds sexy in a partner as part of WHO's Sexiest People issue for 2020.
"I find kindness and authenticity to be some of the sexiest characteristics of a great partner and relationship," she revealed.
We have no doubt Matthew ticks those boxes!
