Big Brother romance? Luke and Rebecca get cosy with intimate chats late into the night

Housemates began to suspect the pair were becoming more than just friends, when they snuggled up for a cosy chat on Luke's bed.

Rebecca sneaked up on Luke and surprised him with her teddy before perching on his bed to enjoy a long conversation.

Budding romance: Luke and Rebecca sat up chatting late last night, fuelling speculation of a developing relationship

It started with Rebecca's revelation that she has a fear of belly buttons - and can't bear people touching them.

But then things got cosy when Luke discovered something shiny was under his bed sheets.

'Did you get my present I left you?' asked Rebecca.

'What present did you leave me?' asked Luke.

'I stole some tinsel from the Karaoke booth and put it on your bed,' giggled Rebecca.

'You're generous,' said Luke.

Later, as the housemates gathered in the living area, the not-so-subtle Kathreya probed Luke on his feelings for Rebecca, who he fondly calls Bex.

'Is she your woman?' asked Kathreya. 'She was on top of you last night!'

Turning beetroot-red, Luke said: 'Rebecca pounced on me, I couldn't physically move!'

'She is your woman.' Kathreya teased.

But Luke tried to defend his relationship - and insisted they were just mates.

'I can't begin to explain how much she is not my girl,' he insisted.

'I could write a political essay on how she is not my girl.'

But Bex overheard and joked: 'Don't make me cry Luke, I'm very upset.'

The flirtatious pair have nicknamed each other pet names Phil (Schofield) and Fern (Britton) after the This Morning presenters.
