Big Brother Luke fears he'll be branded a love rat after revealing his secret girlfriend

After weeks of flirting, Luke and Bex finally shared a kiss in bed last Thursday - possibly in a bid to save the nursery nurse from possible eviction the following day.

Despite Bex's unpopularity amongst viewers for her bitching sessions with recently departed housemate Jennifer Clark, she only received 33 per cent of the votes compared to Mario Marconi's 77 per cent, who was evicted on Friday night.

Another BB love triangle: Luke, who has a girlfriend, shared a kiss with Bex last week

The duo finally put an end to the romantic tension and shared a kiss under the duvet.

However, Luke was forced to admits he has a secret girlfriend of two months on the outside - and feared that he would be branded a "love rat" by the press.

The 20-year-old politics student confided in his fellow Hell Housemates Bex, Sara Folino and Stuart Pilkington that he had even introduced her to his parents.

He said: 'They don't know her that much. Just met once or twice. It’s not as if I was dating her for two years - we'd been to Pizza Hut a few times!'

'That’s enough for the papers, going to Pizza Hut,' warned Mikey.

'I don't think I'm gonna get hammered in the press for that,' said Luke. 'If anything they'll hate you, Rebecca, not me.'

'The story would be very dull unless she lied through her teeth,' he said. 'I think the press have got bigger fish to fry.'
