If you need your memory jogged further, Zoe's personal website will fill you in!
According to her bio, she's a "Go-Getter. Mentor. Presenter. Pharmacist. Entrepreneur. Age-Defying Product Specialist.
"She relocated to Vanuatu for 18 months as an Australian Volunteer for International Development to lend her Pharmacist expertise.
"Upon returning to Australia in 2014 she made her TV debut on The Bachelor and won the hearts of the nation as the vivacious, curly haired, girl next door."
She placed fourth on the love-finding franchise - and while she walked away with a broken heart, it didn't last long!
Zoe moved on with The Voice Australia contestant Sam Ludeman. When they split in 2015, she shared a "final Sam and Zoe" post to Instagram.
Fans will remember Michael's appearance on BIP in 2018, which he made shortly after his very public bust-up with Zoe.
An eyewitness at Sydney's Coogee Pavilion told New Idea the pair had a awkward exchange of words, apparently over their mutual romantic disappointment. "She was saying how disappointed she was in the way he'd treated her, and he kept apologising."
"She said she ‘really liked him until he told her to shush the next morning.'"
We bet she has her fingers crossed a newly-single Michael doesn't arrive in Paradise for round-two!
