Days after entering the CBB house, Lewis and Marnie got together and the pair have been pursuing a romance with each other ever since. They've been kissing and cuddling up on camera, taking naked showers together, and Lewis has even told Marnie he loves her!
Jordan (who has been previously linked to Marnie himself), however, isn't convinced it isn't all for the cameras...
We caught up with him recently and he exclusively told Reveal: "I don't know how real this thing is with Lewis, this romance. I just think they're doing it for a showmance, for a storyline."
Asked why, he said: "It's a bit out of the ordinary."
He explained that Marnie had gushed that Essex boys are so different to Geordie boys, but he points out that 'she already knew that' before CBB, as she has history with former TOWIE star Ricky Rayment.
Jordan added: "She was engaged to Ricky... she knows exactly what Essex boys are like."
He also doesn't think that Marnie has what it takes to win the show.
Her co-stars Charlotte Crosby and Scotty T are previous CBB winners, but Jordan isn' sure Marnie can follow in their footsteps.
"Me, personally, I don't think Marnie is going to win it," he said. "She's got the Geordie Shore fan base, but she's not as big."
Instead, he's rooting for Stephen Bear.
That may seem unlikely, as Bear and Jordan previously clashed over his ex Megan McKenna on Ex On The Beach, but Jordan tells us the boys are friends now.
He explained they actually became mates while filming series five of Ex On The Beach back in April, and now he's rooting for Bear to go all the way.
Commenting on Bear's behaviour in the CBB house so far (he's divided housemates and viewers with his wind up pranks), Jordan said: "I think Bear is doing brilliantly. He's being himself and not playing a character. He says it how he is. From what I've seen… I think Bear is doing more than enough to win it at the minute, he's a dark horse as well and people won't expect him to win it. He doesn't b*llsh*t anyone. I think they see him as a threat.
"He's like marmite. You either love him or you can't f**king stand him."
Ex On The Beach returns Tuesday 16 August at 10pm on MTV.
