Killian Accuses Ashley and Blake of Secretly Hooking Up While Filming ‘The Ultimatum’ Season 4

Killian Grondin accused Blake Robertson and Ashley Wilson of secretly hooking up during their trial marriage when cameras weren't filming on The Ultimatum season 4. Killian and Ashley ended their engagement six to seven months after filming wrapped due to stress from his double leg fracture, with Ashley eventually moving into her own apartment.Viewers questioned why Killian waited to reveal the alleged affair until after the reunion aired, suggesting the accusation was conveniently timed and lacked credibility.Season 4 of The Ultimatum: Marry or Move On may have wrapped when the reunion special hit Netflix on July 22, but the drama seems to be alive and well behind the scenes. Most of the messiness has brewed between Hayley Hendrich and Blake Robertson’s split and assault allegations, as well as Killian Grondin and Ashley Wilson cutting off their engagement after he broke both his legs.Now, Killian is accusing Blake and Ashley of being involved in a major entanglement when the show’s cameras were off during their trial marriage.“I just found out that Ashley and Blake were hooking up on the show while the cameras weren’t around, bro,” Killian said during an interview on Jebin John’s podcast. (And yes, you read that right: Jebin apparently has a podcast.)According to Jebin: He heard the same rumor...from Blake himself. “Blake was telling me all of this shit about what they were doing when the producers were gone, and the cameramen were gone, and they were trying to be real sneaky with this shit,” Jebin replied before calling him and Ashley “manipulators to the max.”Fans in the comments section called Killian out for the “convenient” timing of his accusation, with one writing, “I call BS. This would have been brought up on the reunion if there was any substance. So convenient to bring it up now.”Add Cosmopolitan as a preferred source in your Google search results.Use your Google account to add this to your settings.Neither Blake nor Ashley has responded directly to Killian’s claims, but for what it’s worth, Ashley did seem to have a positive experience during her trial marriage with Blake. During an interview with Tudum, she credited him for helping her see what she was missing in her relationship with Killian.“Sometimes when you’re deeply in love, you can become blind to things that seem so obvious from the outside,” she said. “[The trial marriage] gave me the confidence to stand on my own two feet.”Then again, considering that Ashley is seemingly now besties with Hayley, I find the idea that she was hooking up with Blake a little tough to believe.Before all this went down, Killian admitted that his engagement with Ashley ended six or seven months after The Ultimatum stopped filming because of “stress” that strained their relationship when he broke both his legs after doing a backflip.“She was doing everything for us. I couldn’t cook, I couldn’t clean, and I couldn’t drive myself anywhere. So she was an absolute trooper for that,” he told Us Weekly, later adding that she had “decided to go get a one-bedroom condo behind my back without telling me” and broke things off.Though he claimed they were in a good spot and still kept in contact after their split, it seems like it might be up in the air after his recent accusations against Ashley and Blake.
