Dean, 41, was the first to respond in complete disbelief over the comment and he wrote 'Wow!!!'.
While Sean, 41, added on his own story with the caption, 'This is not OK. Disgusting', he wrote.
He also made a second post backing up his former MAFs co-star saying, 'One of the best blokes I've ever met.'
The confronting message comes after MAFS' Jessika Power, 27, denied Telv's claims that she cheated on Dan Webb with him in December last year.
'No we did not kiss. No we did not sleep together!' she wrote in an Instagram post on Tuesday.
Sharing a photo with Telv on her Instagram Story, Jessika posted a lengthy denial to the explosive claims.
'Another day, another false cheating allegation who I thought genuinely was my friend!' Jessika wrote in reference to Telv.
Despite everything, we already know about Jessika and her history for cheating and lying she maintain that the pair, "caught up for a drink so he could introduce me to someone in the media who could help guide me throughout my journey on MAFS".
'I was completely head over heels and infatuated (sic) with my love for Dan at the time and I would never ever have done anything to jeopardize that,' she continued to write.
Jessika also made it clear that she wanted the former MAFs star to confess to lying about the allegations against her, 'I have asked Telv to be clear this and admit to his lie so we can all move on and be happy family's again.'
However, Telv told Daily Mail Australia that his claims are legit and that Jessika did in fact cheat on Dan with him that night.
'I don't appreciate being called a liar. I also never wanted this to be public knowledge. I reached out to Dan because he was being called a cheater. So I thought coming clean was the right thing to do,' Telv said.
While it looks like, despite the racists online abuse, Telv is sticking to his guns about the allegations against Jessika.
