The controversial Christian took to Instagram hours after the news broke to post up a storm with his sibling co-star Austin.
The outspoken WA native captioned the series of photos 'These little llamas need no dramas' in an apparent dig at the mounting outcry over his drug use and offensive comments online.
Old social media photos obtained by New Idea seem to show the home-schooled culinary whizz holding a bong to his lips as he snaps shots of himself in a bathroom mirror.
'Timr [sic] to be Mexican,' Josh captioned the picture which he shared on Facebook.
'That’s now in the internet forever,' a pal wrote on the now infamous post, prompting Josh to unleash a foul-mouthed rant on a critic who accused him of losing weight 'because of drugs'.
'I lose weight because of drugs? Well you get fat because you’re a Burger eating sexually frustrated hoe,' Josh wrote.
'Come on whos [sic] next?'
