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?”

“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 of tried to f*ck me”.
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 was caught up in a violent, racist fight all caught on camera.
