Speaking to her fellow housemate and TOWIE star Lauren Goodger, Stephanie admitted she had the "worst luck" meeting Spencer on her first night in London and at the time "had no idea who he was".
Stephanie told Lauren how she quickly moved in with Spencer as he swept her up with his charm.
She said: "He was all 'you're my soul mate'… He's so good at what he does."
When asked by Lauren how long her relationship with the Chelsea boy lasted, Stephanie told her: "Until he cheated on me in September."
Although admitting the pair are now friends, Stephanie revealed she only sees Spencer when she has to: "I never hang out with him outside of filming... ever."
The ladies man from SW3 has quite the reputation for having a wandering eye and viewers have seen him cheat on most, if not all, his girlfriends he has had on MIC.
After breaking up with former flame Lucy Watson thanks to his infidelity, Spencer quickly struck up a romance with The Hills star, Stephanie.
The pair seemed loved-up from the get-go sharing steamy snaps while holidaying in Mykonos last summer and even planning to spend Christmas together in Colorado with Stephanie's brother Spencer Pratt and his wife Heidi.
But not before long Spencer was back to his own ways and Stephanie found out her boyfriend had cheated on her too.
Speaking about his split with Stephanie, Spencer said he thought their relationship was never going to last.
He said: "Mine and Stephanie's relationship always had an expiry date... I didn't allow myself to fall deep into the reals of love; she lives in LA so it was more of a holiday romance."
Since Spencer, Stephanie has gone onto enjoy a cute fling with co-star Stevie Johnson after kissing while on a sightseeing date around London. Despite growing close the blonde beauty soon had to return to LA, leaving her to say an emotional goodbye to Stevie before she left.
Now, Stephanie is in the Celebrity Big Brother house and has found herself with an admirer in the form of Gogglebox star George Gilbey.
George told Stephanie he loves her and even made her his very own love token - a handmade paper bowl with the words 'I heart ewww' cut out of it.
As George spent the night away from his housemates last night, Morris dancing in the task room, viewers saw Stephanie admit to her housemates that she was missing him as she told them she loves him too.
Could another romance be on the cards for Steph?!
