TEA-obsessed Jack P Shepherd is set to be bombarded with big money deals after reaching the Celebrity Big Brother final.
But any plans to cash in by signing up to star in television adverts will be blocked by bosses.
It means any with cuppa addict Jack, 37, will miss out.
A TV insider said: “It used to be a lot more strict, but these days ITV are allowed certain partnerships that are permitted on social media.
“The line is drawn at advertising more generally – and absolutely no TV adverts.”
Jack has been drinking endless cups of tea during his three-week stint in the Celebrity Big Brother house.
He amused fans this week when he told housemates he needs to use TWO teabags to mask the “c**p” tasting water down south.
Amid hopes of landing a tea brand deal on the outside, the 37-year-old has spoken about companies not being interested in working on sponsorship deals with him.
A source told The Sun: “Everyone knows money’s tight on the cobbles at the moment and the cast are looking for extra ways to make some dosh.
“He's spoken about promotions and advertising a good few times on the show and pointed out that no one's ever bothered about doing a deal with him.
“However, he's now in the final of Celebrity and is a dark horse to win. He knows that by making tea a part of his personality on the show, that it gives me a good opportunity on the outside.”
Jack is in the final six with , , Danny Beard, and Chesney Hawke.
They are all eagerly awaiting to find out who will be crowned champion during Friday night's finale.
The Sun has reached out to Coronation Street.
