Leaked Big Brother audio reveals exact moment show’s surprising romance kicked off as house was evacuated in fire alert

UNEARTHED audio has revealed the secret conversation between Big Brother housemates Baked Potato and Nathan as their friendship turned romantic.

Fans were stunned to discover the show's most surprising romance kicked off as the house was evacuated in fire alert.

And on Late and Live last night, presenter Will Best shared the moment the pair planned a secret date while still wearing their mics.

Baked Potato says: "I want to ask now.. When we get out, do you want to go to a winery? Just me and you?"

After struggling to hear what she was saying as she repeatedly whispered "winery", Nathan finally replied: "Yes, of course."

He then spilled the tea to Ali about their secret conversation - and plans to date outside of the experience.

Their feelings became transparent when Nathan, Baked Potato and Lily were in the garden last night.

Lily - who was desperate for a snog - dared them to kiss and it ended up exposing their hidden feelings.

Nathan and Baked Potato (Rosie) were whispering to each other how they both had to "run away" from Lily.

The duo quickly retreated to the bathroom as they were both completely taken aback by Lily's actions.

They both asked each other: "Why is Lily kissing us?"

Housemates were told they must call Rosie "Baked Potato" for the foreseeable future after a dare in the first week.

She has grown close to King Charles' former butler Nathan in the house.

It follows Henry and Jordan's romance last series.

The pair are still together now, a year after Jordan won the show and a £100,00 prize.
