This. They don't actually get paid a huge amount by GS. They all make money from appearances on other things and the girls especially make a small fortune from product endorsement as they have massive instagram etc. followings.

Gaz makes a fair bit more money than most of them I believe, as he has invested wisely since he started earning from the show, with things like personal appearances / his own club nights and I believe at this point he actually owns a few nightclubs abroad (party islands, etc.), as well as having invested in other businesses and property. He's probably easily a millionaire at this point.
