Imogen is currently filming on the White Isle for the ITV2 reality show, and recently shocked fans by announcing she and Louis have split.
The couple had seemed oh-so-smitten before she jetted off for Ibiza Weekender, but Imogen later told fans "it's with regret" that she has ended their relationship. Louis, meanwhile, has now shared his side when it comes to their break up, and has accused Imogen of being 'unfaithful.'
Speaking to The Sun Online, Louis claims that Imogen cheated on him during filming with her ex-boyfriend Deano Baily.
He alleges that Imogen rang him on camera to tell him over the phone about the kiss. Louis said: "The way she did it is just brutal, it's the worst way to end a relationship, on the phone and for TV."
"We were talking about marriage and kids," he continued. "We planned to be together forever... I never felt she was harbouring feelings for [Deano]."
While we already knew that Imogen and Deano have shared a kiss while away, it wasn't confirmed whether she and Louis had been dating at the time.
Imogen has not directly responded to Louis' comments and when contacted by Reveal, a rep for Imogen declined to add any further comment to her initial statement about their split.
Imogen had said: "It's with regret that I have chosen to end my relationship of less than a year with Louis. We will always have fond memories together and I hope that we can remain friends."
After Louis' interview surfaced online, he took to Twitter apologising for "spoiling" the next series of Ibiza Weekender, but stressed he wanted his side of the story to be heard.
He tweeted: "Thanks for the support! Sorry to spoil next years Ibiza weekender .. Not playing victim but my side of the story had to be said... And for anyone asking I have not been paid for any stories! I will never slag off Imogen for what's happened...it's done... Life goes on."

Following Imogen's announcement that the pair had split, Louis had teased: "I will be telling my side of the story very soon!!"
He and Imogen had dated for less than a year, and first went public with their romance back in April.
Their relationship came after Ibiza Weekender fans saw Deano admit in the finale of the show's last series that he was still in love with Imogen.
Imogen, however, told Deano it was too late, adding: "I have been waiting for so long for Deano to tell me he still loves me. But I knew that the right thing for me was to walk away with my head held high and be a strong person."
