During her rant in her newspaper column, Luisa also admitted to posing for suggesting photos with her fellow Celebrity Big Brother contestant Dappy, despite them not being romantically involved.
The outspoken star, 26, said: “[Dappy and I] did an interview with OK! magazine which kept you all guessing, perhaps alluding to the fact we were sharing more than just fluttered eyelashes, but never quite confirming it.
“Mainly because we definitely were…NOT.”
Former Apprentice star Luisa also took a chance to swipe at I’m a Celeb contestant Amy Willerton, who was rumoured to be seeing Joey Essex after they left the jungle.
“Look at how Amy Willerton clung to Joey Essex in (and after) the I’m a Celeb jungle, like a blood-sucking leech hanging on for dear life to ensure maximum exposure.
“Any sensible sane human being could see it was an absolute car crash, but it didn’t stop us from willing it would happen. Poor Joey, thank goodness he has now reunited with the lovely Sam Faiers – which is definitely not a showmance.”
And it’s wasn’t just Amy who featured in Luisa’s rant – she also took the opportunity to slam her fellow CBB star Casey Batchelor.
She said: “There was talk that Casey Batchelor wanted to attach herself to Lee Ryan because of press and earning possibilities when they came out the house in fake ‘togetherness.’”
Luisa finished up by questioning who is to blame for the rise in showmances, saying: “Do we point the finger at celebrities who play up to and profit from these showmances, or the public who so desperately want them to happen and devour the headlines of ‘Maybe, definitely, wedding bells, not at all, who cares?’”
