House Rules: Joh Griggs stunned as furious Troy & Bec storm out

Hit renovation show House Rules has been rocked by unprecedented scenes, as a highly successful overhaul of Sean and Ella's house is stained by a screaming row and a shock walk out. 

Even though the show's resident taste guru Laurence Llewelyn-Bowen awards one team a perfect ten, it isn't all smiles.  Fiona is seen screaming at Harry in a tense moment that leaves bystanders shocked.

'Don't you dare!' she is heard raging, 'Pull your head in - you can shove your measurements up your clacker!'

But even that explosive situation pales into insignificance compared to what happened at judgement time in the studio - with Troy and Bec storming out in a fit of fury. 

'Let's go babe,' a disgruntled Troy is heard saying, much to the shock of host Johanna Griggs, who appears completely stunned and mortified as the duo leave the studio mid-filming. 

Later footage of the couple, apparently filmed at a hotel, includes an uncooperative Troy uttering the charming words, 'Blow it straight our your ****.'
