They had appeared blissfully happy over social media the past few months but Imogen announced on Friday (16 September) that she and Louis have called time on their relationship.
She 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."
Imogen and Louis' romance first became public back in April, and the following month she gushed: "Still don't know how I managed to find him but I did. Happy lady."
After Imogen released her statement, Louis tweeted: "I will be telling my side of the story very soon!!"
It was just three days ago on 13 September that Louis had shared a photo of him and Imogen, saying: "Proper missing this one today @imogenweekender ... 2 weeks today."
There's no word yet on why they broke up, but perhaps Imogen will explain more when ITV2's Ibiza Weekender returns to screen?
Fans will now be wondering if Imogen may get back with ex-boyfriend and co-star Deano Bailey, after he admitted during the last series to still having feelings for her.
Imogen, however, told him 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."
But... has she changed her mind?
We've been told that Imogen and Deano HAVE shared a kiss while filming in Ibiza, but they are definitely not together.
So many questions, so few answers as obvs everything that happens is kept under wraps until the show airs on ITV2. It cannot come soon enough, right?
