The pair had formed an unlikely romance in recent episodes and had been on a string of dates, so it came as no surprise that, at Stephanie's leaving party, Stevie was desperate for her to stay.
US reality star Stephanie was emotional as Stevie pleaded with her, but she insisted she had to go home to Los Angeles.
"Stay a bit longer?" said Stevie. "What am I going to do without you?"
Now in tears, Stephanie told him: "I'm going to really miss you. I just wasn't expecting this when I came here. It's just changed everything. You're such a good guy." Stevie replied: "It was out of the blue."
After the show, both Stephanie and Stevie took to Twitter to express their sadness and later shared photos of the times they had spent together.
Stevie tweeted: "Hardest goodbye I've ever had. Miss you @stephaniepratt x."
The Hills star Stephanie replied to Stevie saying she missed him too, but also admitted that she regrets leaving, "I should have stayed," she wrote on Instagram, with a screenshot of her emotional goodbye.
Stephanie had earlier told fans on Twitter that watching the show back would be "too hard to relive".
Along with most of the MIC cast, Stevie is currently in New York filming for the forthcoming spin-off series, but there are currently no plans for Stephanie to join him in the Big Apple.
A rep for the show tells Reveal: "At this stage, there is no intention to film with Stephanie."
The pair first became romantically involved after Stevie took Stephanie out on a sightseeing tour of London. Their first kiss came as a surprise to some, especially as Stevie had previously taken Riley Uggla on several dates.
Despite it being unexpected, Stevie and Stephanie were soon inseparable and, judging from the new photo's they've uploaded, they seemed to be pretty smitten with each other!
Stevie posted another snap to Instagram of the pair last night, and said: "All good things come to an end - but we had a blast! @officialstephpratt."
We'd love to see a Stevie and Stephanie love story!
