Yeah he still makes content with her, they've been together for years now.
Josh and Mariah had a very messy breakup, she apparently cheated on him and he withdrew his permission to feature in any of her content, so she had to wipe it all, and withheld a HD with unreleased stuff (including the Dutch gloryhole part two) which will never see the light of day. She's engaged now to a different guy and is very much monogamous - any references to hookups and tinder dates etc. are just for the content - but she's still freaky as hell and I think genuinely loves showing off. She has a 'proper' job and everything, this isn't her main hustle
