Heavy D - real name Colin Newell - was booted out of CBB last night having gone head-to-head with Lewis, Stephen Bear and Renee Graziano.
And now out of the house, he hasn't been shy in giving his opinion on the show's remaining couple.
Speaking to the Sun Online, Heavy declared: "That's fake! It's a showmance.
"They're not stupid! They've got the same agent, I know a showmance when I see one. "
They knew each other before they got on the show. Showmance."
TOWIE star Lewis and Geordie Shore's Marnie were soon locking lips once this series of CBB had kicked off and this isn't the first time their romance has been branded a showmance.
But their agent previously said: "Marnie had not pre-planned any kind of romance in the house with Lewis. They have met once before they were even with the same agent. They were not aware of each other going into the house and haven't planned any kind of relationship for screen time. These claims are completely factually incorrect."
Lewis' mum Claire has also spoken out and rubbished claims that her son's relationship with Marnie is fake.
"People are saying it's a showmance and that's absolute rubbish," she also told the Sun Online.
CBB continues at 9pm on Channel 5.
