The Celebrity Big Brother housemates will enter the diary room tonight to give their first eviction nominations of the series, with one set to receive a pardon from house president Kirstie Alley.

In scenes shown in tonight’s episode of the Channel 5 reality show, the contestants will let loose as they explain who they would like to see leave first.

Former The Only Way Is Essex star Dan Osborne is set to put US reality star Natalie Nunn’s name on the chopping block after her behaviour made former Love Island contestant Gabby Allen feel “intimidated”.

Explaining his decision Osborne will say: “It’s a tough one as I do really like Natalie. I get on well with her. She’s been a bit different today though.

“I’m very close with Gabby and I’ve become very close to Hardeep (Singh Koli) too. She was very rude to Hardeep about his cooking and then she was rude to Gabby as well and made her cry.

“I don’t want to see people that I get on with really well and that I like crying. It’s causing a bit of a bad atmosphere.”

Osborne is set to comfort a tearful Allen, who will break down and say after Natalie told her that she is “fading into the background” on the show.

Osborne will tell Allen: “You should say in return to that ‘I’d rather fade into the background, whatever you mean by that, then get involved in other people’s business’.”

Hollywood actress Alley will inform the housemates that as house president she will grant immunity from eviction to the person she believes deserves it the most.

Each contestant will present their case for why they should be saved to Alley in the oval office. Osbourne will suggest it should be him as he helped clean Singh Koli’s hair out of the bath.

Celebrity Big Brother continues on Channel 5 tonight at 9pm.
