Nobody ever said that being in the Big Brother house would be easy, but new housemate Rebecca has got a challenge on her hands.

The 19-year-old student was voted to enter the famous residence last night, but rather than enjoy her first evening, they set her a secret mission straight away.

The bubbly brunette was told that she would have to become someone's favourite housemate in order to win immunity from next week's second eviction.

Rebecca was called into the diary room shortly after entering the house, where Big Brother asked her: 'Made any friends yet'

'Ahh I don't know,' she replied, before Big Brother told her she better start on making some.

The secret mission was then explained in full to the loud contestant, including the fact that she had only two days to become someone's favourite.

Before Monday's nominations, all of the group will be asked who their favourite is and Rebecca needs just one of them to say her name.

If she fails to do so, then the brunette will automatically face the public vote – the same rule applies if anyone else finds out about her secret task.

'This is the worst case scenario in my life man,' she told Big Brother while holding her face in her hands. 'Right that's the way the cookie crumbles, I will be somebody's fave housemate.'

Meanwhile, someone else was experiencing torture of their own as male model Arron volunteered to let Lauren wax his chest.

The 23-year-old was laying on the bed while the blonde used her own waxing strips to get rid of his hair.

However, Arron tried his best to keep his cool but he didn't seem too impressed when fellow housemate Chris got involved.

'Let me pull one, the first one,' the bailiff/doorman shouted. 'I'm horny to pull one!'

However, as Chris removed the first strip he accidentally hit Arron in the head, leaving Lauren to do the rest.

Once she's removed all of the hair, the 20-year-old, who was wearing a tight pink dress, applied baby lotion to Arron's chest.

'Oh brilliant, check you out,' he told her as she stood in front of him. 'Banging view.'

'I suppose you deserve it after that,' she replied as she continued applying the cream. 'That is one beautiful chest my love.'
