Celebrity Big Brother has introduced a nominations twist before the finale, giving half the housemates twice as many votes as the other half.

The members of the winning team of a Christmas task will get to make two nominations, while the losing team members will only get to make one.

The nominated housemates will join Bear in facing the public vote because he has an eternal nomination.

After hearing the news of the twist, Bear said: “I’m going to see some surprises. It’s D-Day. It’s on like Donkey Kong.”

Ricky added: “With two nominations you have to put up somebody you’ve been getting on with.”

The housemates’ choices will be shown in Monday’s episode.

In footage that was aired on Sunday night, contestants woke up to find Father Christmas in the living room and Shakin’ Stevens’ hit Merry Christmas Everyone playing.

Merry Christmas, one and all. #CBB https://t.co/KpoM2ShkLN

In the Diary Room, Mob Wives star Renee revealed her best and worst Christmas presents to Big Brother, saying her best was “when my father came home from jail” and her worst was finding out “my husband, now ex-husband was having an affair, and that the girl was pregnant”.

On Friday The Only Way Is Essex star Lewis Bloor was booted off the Channel 5 reality show alongside radio DJ James Whale as part of the first double eviction of the series.

Celebrity Big Brother is broadcast on Channel 5 at 9pm.
