If we're being honest, we're not too sure that many ever believed his boasts of being a millionaire ex-Sugar Daddy.
But according to his former girlfriend, Danielle McMahon, Dexter's lies don't there.
“Papping celebrities was his main source of income," she revealed (confirming what we really already knew). “He claimed to own a strip club but he was actually just a waiter.”
And as for Dex's famous £122,000 bar tab, Danielle told the Daily Star: “No champagne bottles were opened at all. They brought out about 20 and made a big fuss, with confetti and everything.
“The bottles sat on the table for an hour then the staff took them away.
“It was really embarrassing but I was just in awe that so many people bought into it. I wanted to scream that it was fake.”
As well as discussing Dexter's manhood, Danielle also claimed that wannabe celebrity publicist tried to blag is way to get free meals.
She said: “He told the manager: ‘I’ve got a fanbase of 20,000 people on Twitter. I will go to town and say I’ve had an awful experience.’
“Everyone was looking. I was so embarrassed.”
Dexter faces eviction tonight against Jemima Slade, with one of the pair leaving in this evening's live show from 9PM on Channel 5.
