Inbetweeners star James Buckley became Cameo's first UK millionaire after joining the app just two and a half years ago. The 35-year-old has amassed $1million or £930,00, simply by sending fans personalised messages for a fee.
The actor played Jay Cartwright in the hit show for three series and two movies opposite Simon Bird, Joe Thomas and Blake Harrison. He has since said Cameo had given him "financial freedom" to pursue his passion projects.
The platform has proved to be a particularly successful side hustle for many other actors, sports stars and comedians. With this in mind, Business Name Generator revealed the names of five more stars who have made massive amounts of money using the Cameo app. And some may come as a surprise.
