Speaking to Josh Pihlak on her Sea FM breakfast show, the groom praised Lizzie for putting herself out there again, after her awful experience with Sam Ball.
"Good on her for coming back and being able to do that," he said to which Heidi quickly responded: "No, as if. You can't do it again. If you'd gone through it [before], you'd be like, 'Oh no.'"
Current bride Mishel Karen sat down to chat exclusively to WHO right after the reunion was filmed, to berate Lizzie, calling her "annoying" and "fake".
"Far out, it's frustrating as f**ck when people weren't real. Out of the originals, no one," she said. "But out of the intruders, probably Lizzie. She annoyed me but I just kind of ignored her.
"She's fake," she said. "She was in it for fame. Like, no one would ever endure this twice. If you had sanity, would you go through the whole experiment as we went through again?" she asked her TV, Steve Burley.
"She wants to be Insta famous, she wants an extra 150 not 150, 000 followers."
Steve actually defended Lizzie.
"Last year, she was only here for five minutes. We did the whole experiment so it can suck the life out of you. But she only id it for a short time and this time."
But Mishel didn't give up, claiming that Lizzie got special treatment from production.
"She didn't do it like us. She did it in first-class while we did it in third class... No, the luggage area of the plane."
