<i>Married at First Sight:</i> ‘Toxic’ Hayley and David booted by experts_1

The Married at First Sight experts have gone rogue, ditching the show's strict commitment ceremony rules and asking a couple to leave the experiment.

The group was outraged when polarising bride Hayley Vernon tried to hold her groom, David Cannon, hostage by writing 'stay'.

This decision follows controversial footage, dubbed #toothbrushgate, that showed David using Hayley's toothbrush to clean a dirty toilet bowl.

Just last year, the experts allowed contestant Jessika Power to string along her TV husband, Mick, for weeks so she could continue her affair with a fellow contestant, Dan Webb.

The experts then let Jessika and Dan re-enter the experiment as a couple.

Ex-contestant Elizabeth Sobinoff is also set to return to screens this week for a second shot at love after she was cheated on by husband Sam.

Standards or not, the MAFS team know their way around a scandal.

It seems this season has reached a new level of pettiness – and we're here for every second.
