Former Married At First Sight star Billy Vincent has unleashed on his former channel nine co-star Martha Kalifatidis in a lengthy Instagram rant.
It all began when makeup artist Martha, who is still dating Michael Brunelli, posted a photo of herself sporting an anti-bullying t-shirt, which is part of a worldwide social media campaign calling upon influential figures and families to post an image online wearing a “Hero” t-shirt.

The t-shirts are designed by Australian label Auguste who has partnered with the Alannah & Madeline Foundation’s National Centre Against Bullying and international organisation The Cybersmile Foundation to speak out against bullying and advocate for the right to be free from violence.
However, the reality show's 'good guy' Billy was far from happy with the brand's decision to ask Martha to be their advocate.
“I really hope this anti-bullying company didn’t send her these shirts,” said Billy in a lengthy Instagram video.
“Because that would be really f*king stupid. “Why would you put her as the face of anti-bullying?” quipped Billy, referring to the many times Martha was accused of bullying on the Nine Network show.
He concluded: “Martha would attach her name to a bottle of poison if it furthered her career”.

The rant comes weeks after he was involved in a heated online exchange with his other MAFS costar, Jessika Power.
Jessika, who had her controversial relationship with Daniel Webb, kicked off the tiff by calling Billy a “soft-c*ck”.
“I shouldn’t say this,” she responded, before adding: “Billy, 100 per cent, that guy was a b*tch on the show.”
When asked to clarify exactly why Billy was a “soft c*ck”, the 26-year-old - who was partnered with Mick Gould on the show - replied, “I mean where are your balls?”
Billy was quick to respond to the blonde bombshells jabs, and it didn't go down well after he uploaded his own series of Instagram videos.
“Jessika people in glass houses shouldn’t throw stones,” said Billy, who was married to the outspoken Susie Bradley on the hit reality TV show.
He continued: “Fair enough I was a bit of a soft c*ck on MAFS, but lucky enough or you would have tried to f*ck me”.
This is an obvious swipe at Power, and how she planned a hook-up with other members of the show while 'married' to Mick Gould.
Vincent also took a swipe at the MAFS star's father and brother, adding: “Jessika...I doubt I’m the biggest b*tch on the show”.
This shocking outburst is just the latest in a string of MAFS controversies after contestant Cyrell Paule was caught up in a violent, racist fight all caught on camera.
Later, the owner of the cafe denied the story, saying she wasn't involved.
