In the latest episode of the show, viewers watched Emily Colley's EOTB arrival, surprising THREE of her exes.
While Geordie Shore's Gary Beadle didn't remember who she was, Morgan Evans and Rogan seemed pretty happy to see Emily stroll up out of the water. So much so, that Rogan forgot all about ex-girlfriend Jess - who he had labelled his "future missus" not too long ago - waiting back at the villa for him...
Known for being a bit of player when it comes to the ladies, Rogan was soon showing why he has such a rep after rocking up to the EOTB villa.
On his first night, the Dreamboy shared a cheeky kiss with Kayleigh Morris before swiftly moving onto Britain & Ireland's Next Top Model star Anita Kaushik.
Despite enjoying a flirty fling with Rogan, Anita was left "gutted" when he quickly ditched her for his ex Jess on her arrival. Seemingly smitten with his former flame, Rogan was seen telling his co-stars: "I don't see [Jess] as my former girlfriend, I see [her] as my future girlfriend."
But it looks like any chance of a rekindled romance has now been well and truly dashed!
After greeting Emily on the beach, Rogan was later seen whisking the brunette beauty off to bed while ex Jess looked on.
Recalling her ex-beau's antics Jess said: "I said as a joke to Anita 'imagine if he goes off with Emily tonight, imagine if she is in his bed'.
"Then, I open my eyes to Rogan taking Emily to the bed we shared!
"For him to have the audacity to drag another girl off to bed in front of me... I was like 'you have got to be joking me'. You sir, are a tw*t!"
Explaining he just couldn't help himself, Rogan claimed: "Whenever me and Emily have a drink, we seem to get it on. It kind of just happened naturally."
And to rub even more salt in the wound, he then shrugged Jess off as someone he "barely knew" - not quite the "future girlfriend" he was gushing about last week.
That's definitely not going to sit well!
He added: "I knew [me and Emily] would upset Jess, but I didn't know which one I would regret more. Hurting the feelings of someone I barely know and have been getting on with a bit? Or having this once in a lifetime opportunity to hook up with birds and throwing it away?
"I ended up going with my gut, not my heart.... well, maybe not my gut."
Ex On The Beach continues next Tuesday (17 February) at 10pm on MTV.
