Things have got steamy on the set of The Block NZ.
Spy has learned members of rival teams in the TV3 reality TV series were busted snuggling up under the covers.
The teams are fighting it out for DIY supremacy and a $100,000 top prize — plus post-auction profits.
But members of two teams were caught on camera "bonding" in bed.
MediaWorks is remaining tight-lipped over who was involved but their identities will be a short-kept secret, as a PR insider has confirmed the footage will screen in an upcoming episode.
"There is no doubt having friends as teammates, rather than couples, has changed the dynamic on set this year," the insider said.
"They’re a very social bunch and understandably they have become close through this shared experience. I can imagine there have been some cold nights on set while we’re mid-build so I guess anything could happen."
Spy understands the nature of the footage will allow viewers to decide whether it is a case of friendship or a budding romance.
So who could have been busted by the film crew?
Out of our singles, we have Dunedin DIY-er Emma Diamond, who in a brutal fashion, previously played down any romantic hopes fans may have had about single Wellingtonian flatmates Sam Cable and Emmett Vallender.
Dylan Guitink (Dylz jnr) previously told Spy that his "sort-of relationship" in Mt Maunganui has been put in limbo until after the show and told us he had a penchant for blondes.
Or could it be one of the show’s smartest contestants, Christchurch-based forensic scientist Niki Osborne?
