I think Jessika, Melissa and Heidi defo only there for the fame. Although I really like Heidi so far!
From the lads I reckon Mike?
Yes to Jessika, she definitely has that insta-look and spends every hour on her phone. Mike seems like someone who wants to be a fitness guru type. It doesn't seem to be a very good career choice though! Most of the previous contestants have 100-150k followers, so they can't be making huge amounts of cash.
Melissa and Heidi seemed to have OK careers and be quite independent, so I'm not sure on them. That Ines woman seems to be casting herself as the villan to try and get attention, so I'd put money on her now being an 'influencer'.
