Stacey and Ssh were the resident lovebirds on My Kitchen Rules who swiftly won the hearts of Australian viewers with their laid back, down to earth charm.
Speaking to New Idea back in January about their picturesque life together, it’s clear engaged Byron Bay sweethearts Stacey, 27, and Ash, 34, were head over heels for each other.
Dishing on how they first met, Stacey revealed: "We actually met six or seven years ago. Ash was living here in Byron and I was living in Adelaide, and I was travelling to Byron every three months because I just loved it so much.
"I’d come and stay as often as I could and so I met Ash in one of the clothing stores here that he was working in at the time. We just clicked but it was nothing romantic. It was just purely friends so we added each other on Instagram."
"Yeah I creeped on her," Ash added.
Congratulitons you two!
