Someone under her TikTok comments in her last post is adamantly claiming she cheated on Carmie in Ibiza with a guy named Ross. She also claims that Kate blocked her on IG for revealing it. She has 20K on TikTok and 7K on IG. Kate is actually following this Ross guy on IG and TikTok, and funnily enough, Isseyy follows him too and he follows both. He appears in her Ibiza vlog twice and also Millie's. He was seemingly on a lad's holiday. Now that girl claiming she knows Kate cheated isn't giving any details atm and could just want attention, but I thought I'd mention it in here lol. With Millie being there that seems like it would've been difficult unless Millie just dgaf, but Issey following when she wasn't even there is kind of odd.
