Everyone has been predicting romance for these two housemates (including Lewis' former TOWIE co-stars) and it looks like things are now heating up for the duo.
In a new video shared by Channel 5, Marnie and Lewis can be heard sharing a quick smooch while going to get drinks from the storeroom...
Oo-er (though we must point out, they share the same agent #justsayin').
In the clip, the pair can be heard saying, 'cheers', as they opened their drinks before kissing - albeit briefly. Marnie and Lewis are then heard laughing, before they emerge from the storeroom with pretty big smiles on their faces.
Channel 5 have also now shared a screenshot from tonight's episode and it's picture proof that Lewis and Marnie do pucker up!
Fans have noticed sparks between the pair and in last night's episode, Lewis was seen talking about Marnie with his fellow housemates. He told Sam Fox: "I think she's a nice girl and I think she's fit... I basically wouldn't want it to work that Steve got in there first, but I'm not the kind of guy to rush things."
Sam advised him: "Just be the charmer that you are, and the gentleman that you are."
"We're so different, I love Steve to pieces but he's so brash and confident," Lewis explained. "I like to think I'm a little bit sharper."
We can't see Bear making a move on Marnie, though, as he is currently dating Gaz Beadle's ex-girlfriend Lillie Lexie Gregg.
Lewis and Marnie's kiss comes after her ex-fiancé Ricky Rayment claimed that Marnie and Lewis have already had a "fling."
He was questioned about Lewis and Marnie potentially striking up a romance and Ricky replied: "I wouldn't be surprised if [Marnie and Lewis hook up], I'm sure they've had a fling before. I won't be watching..."
Marnie's Twitter account, however, hit back at Ricky's claims and insisted they were "completely untrue."
Marnie was last romantically linked to her Geordie Shore co-star Aaron Chalmers, but recently revealed the pair are not dating (despite the photographs of them holding hands and kissing while filming for series thirteen of Geordie Shore) and "need to be single."
