Sienna Mae's cancellation started in spring 2021 after weeks of speculation that she and Jack had potentially called it quits. Then, Mason Rizzo, one of Jack's close friends, offered additional detail on what happened between them on Twitter.

In the tweet, which has since been deleted, Mason accused Sienna of repeatedly sexually assaulting Jack in spite of the fact that Jack had established clear boundaries in their relationship.

Mason also said that Sienna told Jack to kill himself and that she had a history of being verbally abusive, often prioritizing her own growth over everything else.

In a follow-up tweet, Mason explained that he had deleted his original tweet after all parties involved in the matter agreed that it would be best to handle the situation offline.

At the time, Sienna addressed the allegations in a now-deleted post on Instagram, saying that the allegation was false.

"Friends fight and relationships sometimes change, but allegations of a criminal act are not to be thrown around loosely," she said. "Making an untrue sexual assault claim is never okay. I'm beyond saddened by this situation. In order for all of us to move forward, I will be taking this offline with Jack. Thank you to all who have reached out with love and concern."
