Their shock split comes just months after the reality TV star waxed lyrical about her bar owner beau in an interview with TV Week.
“When you know you know,” she said at the time. "I first met him briefly at his bar in Melbourne Romeo Lane," she recalls.
"Then we met again properly about 18 months later at a function. We started talking there and we've just not ever ceased since really. It's pretty cool."
Melissa told the publication that they mutually decided to get engaged just three months into their relationship and tied the knot just two months later.
"I planned our elopement in between takes while filming another TV show [SBS's The Chef's Line]," she explained.
"When that wrapped, we went to Joshua Tree in California and eloped. It was all very fun."
To celebrate their third anniversary, Melissa penned a moving tribute to her husband on Instagram, writing: "It was probably a sign that [Joe] and my wedding photos look cinematic, because life since then has been a non-stop blockbuster of action, drama, comedy... and of course romance. 3 years married to you feels like a lifetime, and a split second at the same time."
The couple has an adorable cat named Ghost, with Melissa previously telling TV Week they were very "happy" as a family of three.
"Everything's so good as it is," she said. "I'm really happy."
