MARRIED at First Sight Australia viewers were furious when Sam called his ex Elizabeth a "dementor" after she snubbed him at the dinner party.
On the E4 series, outraged fans watched as the shameless 26-year-old made the nasty comment behind her back.
Lizzie chose not to talk to her ex-husband after he had an affair will fellow bride Ines.
But instead of reaching out to her at last night's reunion, smug Sam chose to call her names.
Speaking to the camera he said: "Seeing Elizabeth walk in that room tonight was… frightening."
Talking about her manicured nails he said: "Look at the claws. I'm getting intimidated."
Sam went on: "It's like one of those dementors out of Harry Potter entering, just sucking the life out of me."
"I'm trying to just stay out of it, but I'm sure I'll get sucked in somehow by the Dementor."
But viewers didn't take kindly to his comments, with this one saying: "How can Sam be so mean towards Lizzie when he's the one in the wrong?"
While another was furious: "That's not on! Sam shouldn't call Lizzie names."
This one tweeted: "Sam really is hurt that Liz ignored him and is begging for her attention. I hope she does not give him any."
This wasn't the only shocker in last night's episode as Cyrell was physically restrained in the most explosive episode ever.
Gobsmacked viewers watched furious Martha throw red wine over Cyrell's head after losing her temper at the dinner party.
Meanwhile, Sam recently lifted the lid on his affair with Ines claiming it was "fake".
On the E4 series, outraged viewers watched the pair cheat on their partners and spend the night together in a Gold Coast hotel room.
They eventually admitted to their infeditlity and left the show - but not with each other.
Sam was put off when Ines wanted to know if they "had a future together" and they didn't continue their relationship.
But now the 28-year-old Aussie claims the romance was staged by producers after they forced him into acting a certain way.
Taking to his Instagram Story, Sam claimed: "They pulled me into a dark room and asked me to do the Ines scenes - they set that up. They made Ines DM me on the phone, that was all staged.
"I did what I was asked to do with all of that. I didn't really care what it looked like. I was in the zone. I've acted before in TV commercials and it was a job for me.

He continued: "Then all the Ines stuff started happening. I throw her on the bed on that date night - not even five seconds later, the producers come in and de-mic you.
"I didn't sleep with Ines that night, that didn't happen. I didn't sleep with anyone on the show... mark my words."
