We wonder what Lewis Bloor will make of that one?!
Back in May, Marnie had enjoyed a night out with Mike and shared Snapchats of herself with the Essex boy at Bianca Gascoigne's Gaslight.
Now, reports are claiming that Marnie and Mike actually hooked up that same night, with a source telling Daily Star: "They were all over each other from the get go, they tried to keep it discreet but no one was fooled... They were kissing and hugging in front of everyone – they didn't seem to care who was watching."
Mike himself appeared to confirm that he and Marnie have history, telling the paper: "Yeah, we got together... Could I pull her again? Of course I could. Don't be silly, that's an easy question."
A rep for Marnie declined to comment when contacted by Reveal.
Marnie is currently appearing on CBB and fans have watched her strike up a romance with Mike's former co-star Lewis Bloor.
While some have questioned whether the pair are putting on a 'showmance', Lewis and Marnie have appeared pretty smitten onscreen and were even heard telling each other that they are already in love.
Although, we're not too sure Lewis will be best pleased to hear Mike's claims about himself and Marnie, as the boys have clashed in the past about girls.
TOWIE viewers will remember Lewis and Mike had come to blows over Nicole Bass. Lewis had been trying to woo ex Nicole to rekindle their romance, but was thrown by Mike as he also tried to pursue Nicole at the same time.
It led to the boys having an explosive showdown, where Lewis told Mike: "Mate you're 20 years old, the only thing past it is your hair line. You talk about my weight, I can lose weight but that hair line you need a transplant for. Standing here you look like McDonald's arches. I don't know whether to have a row or order a Big Mac."
However, Mike appeared to put their feud behind them and had shown Lewis his support on his CBB debut.
As Lewis entered the house, Mike tweeted: "We've had our fair share of rows in the past but wishing @lewis_bloor luck! Do Essex proud."
