Flirty Rebecca and Luke finally share a kiss in the Big Brother house

The pair have been nearly inseparable since entering the house but have repeatedly denied they have romantic feelings for one another.
   
But since learning on Tuesday the brunette is up for eviction this week, the duo have been making the most of their time together.

Sealed with a kiss: Rebecca and Luke get up close and personal

On Thursday afternoon, Luke began the teasing by accusing Rebecca of fancying him. 'You want me,' he taunted, 'it's as simple as that.'

'You want me, Luke,' she replied.

'If I wanted you I could've had you by now,' Luke declared, with Bex responding: 'No, you couldn't. That suggests I would have wanted you and that clearly isn't gonna happen.'

'I think you'd better make the most of it,' Mikey interrupted, 'in case she goes. Keep us up all night.'

Lip service: Luke dives in for a kiss

'One night of full-throttle passion?' suggested Luke.

'I would never do anything of the sort in the Big Brother House,' Rebecca said.

'Oh Rebecca,' sighed Luke, 'it must be tough being you and wanting me but you can't have me.'

Rebecca said she wouldn't kiss the politics student if she was sober but added: 'I'm drinking tonight, though, and I've got my beer goggles on.'

Well refreshed: Rebecca had her 'beer goggles' on

Luke laughed: 'I'm going to look like a member of Hanson to her tonight then!'

But after hopping into bed together later that night, the pair could hide their affection no longer. 'Just kiss me,' Rebecca murmured, pulling him close.

'I can't, just go to sleep!' Luke whispered. 'The cameras!'

But when a rejected Rebecca dropped her head in embarrassment, Luke finally made his move, passionately pulling her face toward his and leaning in for a kiss.
   
But after less than a minute, Rebecca pulled away, burying her face in his chest and giggling.

'Please don't tell me I just did that,' Luke sighed. 'Oh my God!'
