Hilary Duff is the next 'Bachelorette' ... of Tinder -- she's shooting footage of all her dates setup through the app ... and there's a chance it could turn into a reality show.
Hilary recently copped to right swiping a bunch of guys on Tinder -- 9 at last count -- and even went on a first date this week with one of them. Sources with direct knowledge tell TMZ ... cameras were rolling during the date at a bowling alley.
