The date of the very first time someone will be kicked out was revealed mid-way through the show last night.
With £100,000 at stake for the contestants, pressures of eviction have already begun, with the first set to take place this Friday.
On the first night, Big Brother kicked things off by giving the 16 new housemates a challenge.
Olivia Young was put up for eviction during a brutal game of pass the parcel.
When Jenkin was asked who the most difficult housemate to live with was, he chose Olivia as he felt the pair had not “gelled”.
As a result Big Brother announced that she was instantly nominated for eviction.
The 23-year old confided in her other housemates. She later cried in the Diary Room.
Further on in the show, Olivia was presented with a chance to alter her destiny and secure immunity through a secret task.
Olivia is a dancer from Glasgow. Prior to entering the show, she believed she was the best fit because of her party lifestyle and her reputation for having a good time.
She had also said that she was looking forward to being in a “completely alternate universe” living in the Big Brother house.
