Whilst fans were quick to share their top Olympic hits that they requested Delta to play, many couldn't get over her sweet throwback snap.
"This photo is so cute 😍" one exclaimed.
"Just a baby," mused another.
"So cute, and look at those bangs!" a third penned.
Despite having the same name as the deadly COVID variant currently raging across Sydney, Delta has been keeping fans entertained with her weekly Bunkerdown Sessions.
So far her themes have included Disney songs, iconic duets as well as the upcoming Olympics anthems.
"Sending you all lots of love from our living room, to yours," she sweetly wrote on Instagram.

By Delta's side both musically and in life is boyfriend Matthew Copley.
The couple were first spotted together in early 2018 but the Born To Try hit maker tends to keep her private life, private.
"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,” she explained in May last year.
