We watched Ali and love interest Grant Kemp declare their love for each other, discuss having babies, exchange commitment rings and walk off into the sunset together - only to find out it was over before we'd even known it had begun.
As it was announced that Ali would become Australia's next Bachelorette, rumours swirled about what "really" went down between the pair after the show, with reports that Ali had dumped Grant after he tried to have a threesome with her.
"Ali travelled to LA to see him after the show, because she was considering moving there and really thought it was going to work out,” a source told Woman’s Day. “But he tried to make her have a threesome with one of his mates and so she got scared and came running home."
However, now Grant is sharing his side of the story, claiming the Aussie beauty "cheated on him" with his best friend.
"I don’t understand why she would do something like that," Grant tells New Idea. "She definitely had me fooled, that’s for sure."
"The third or fourth day she got here, we went out and this night – when all this stuff happened – I had people over after going out to a club," Grant explains. "I live in a gated community so I have to go down and let people in sometimes.
"So, I leave my house with my friend Sabrina, to go and grab my friends and bring them back upstairs, and when we walk back inside, we come up the stairs and she is hooking up with this dude."
New Idea claims to have obtained a series of text messages between the couple, with Ali reportedly begging for forgiveness.
"She starts blowing up at me the next day saying: 'I’m so sorry. I was wasted. That’s not me.' And I was like, 'No, I don’t want to see you,'" Grant explains further.
"I told her to stop talking to me: 'I’m about to block you', so that’s what I did, I blocked her and she flew home the next day or something like that.’
Ali is yet to comment on this story.
