Demi had just gotten off her 8 hour flight which landed her at London. Even though she is used to flying she still hasn't got over her jet lag which was starting to kick in because she would of been bout 6 hours behind England time when she was in America. She was so nervous due to her having to go to meet the producers so they could explain to her what was expected of her to do while she was in the celebrity big brother house.

They had explained everything to her and it seemed quite hard because she had to hand over her phone which she was used to having on her all the time so that would take Demi quite awhile to get used to. During the meeting, they didn't tell her much about her housemates that were in the house apart from their names which are:

Luissa Zissman was on a show called the Apprentice

Ollie Locke who is on a reality show called Made in Chelsea

Sam who is on reality show called The Only Way Is Essex which is known as TOWIE

Casey who is a British model

Jim who is British comedian

Dappy who is a singer but was originally famous for being in the British group Blue

Evander who was a heavyweight champion

Jasmine who isn't really famous but is American but has appeared in movies

Jim is a comedian

Lee Ryan who was from a famous British band called Blue

Linda who is famous Nolan

Lionel Blair who was a singer

Liz who was a British journalist

She was really nervous about going into the Big Brother houe because she didn't know anybody in the house so she was new to everything and they have already formed close bonds over the tthree days that they have been in there - she had nobody so she was really anxious and just wanted to go into the house.

In the house

All of the housemates were chatting and laughing about all the different things that ere being said from different sides of the couches and some people in the kitchen. No-one knew about their secret housemate that was arriving in five minutes all they knew was that something was going to happen.

They knew this because Big Brother called them to the dininhg room just moments before.

"Celebrities, you have been called to the dining room for a reason and that reason is that there is a new arrival coming into the house in just under five minutes" said Big Brother in his loud voice

All of the housemates suddenly went loud again after being quiet through Big Brother's announcement only making eye contact throughout his speaking. No-one knew who the new celebrity was but everyone knew that it would cause different dynamics throughout the house.

Everyone were oblivious to the fact that it had been five minutes so there was a sudden sound of a doorbell and they knew that there knew housemate was.

They were certainly in for a shock.

All the celebrities stood up just in time for there new celebrity to walk through the house. Demi Lovato had walked in.

It was safe to say that everyone was shocked.

The question running through everyone's mind was is everything going to change?
