Bristolian Josie Gibson is odd-on favourite to win Big Brother tonight

BRISTOLIAN Josie Gibson is odds-on favourite to win the last ever series of Big Brother tonight.

The final result depends on a public phone vote, now under way.

But by last night bookmakers were so confident of the result that some gave ex-sales rep Josie odds of 20-1 on, which means gamblers wanting to back her would have to wager a £20 stake on the result just to win a pound.

Josie's family say they knew she would make it to the final right from the start.

The 25-year-old, who lives in a log cabin next to her aunt's house in Westerleigh, near Yate, was the first to go into the Big Brother house this year – and her relatives are sure she will be the last to leave.

Her auntie Kay said: "She's got to win it. She's the best one left in there."

There are only five housemates left and tonight the winner will be crowned and handed a £100,000 cheque.

But it will not be the end of their Big Brother experience as they will be sent back into the house for two weeks with contestants from previous series for a spin-off show, BB Ultimate Housemate.

Josie's huge family are all behind her – including her three brothers, two sisters, mum, auntie and dozens of cousins.

They have had T-shirts printed with a photo of her, saying: "Team Gibson – Josie to win."

Her 19-year-old brother Josh said: "We are all really proud of her. And she has been the person in there most proud of their home city – she is always talking about Bristol, and even got an Australian singing the Wurzels.

"I really hope people vote for her – she has been brilliant in there, so genuine. She hasn't had a game plan."

Josie is known by her family as "Moo" and "Boo" – so when the national press came knocking at the start of the show asking for "Josie", one of her cousins turned them away, saying he didn't know anyone by that name.

She attended Brimsham Green School in Yate and The Ridings in Winterbourne, and has held several jobs over the years across Bristol and South Gloucestershire.

The ex-financial sales rep grew up in Yate, moving out of home to live with her aunt when she was about 14, and spent a year living in Lawrence Hill four years ago.

Her cousins and brothers say she is the "life and soul of the party", and enjoys nights out at city centre nightspots Dojo and Dragon Kiss as well as the Thekla and various spots in St Paul's.

The talk of the Gibson household is evicted housemate, Australian John James, who romanced Josie when he was in the house.

Her little sisters have got their outfits ready for the wedding, and run around the house wearing a makeshift veil.

Her mum Amanda, 44, of Yate, said: "What you see on the TV is what she is really like, but maybe she is a bit more bubbly at home.

"We have all been glued to the TV watching it day and night, and her little sisters are so excited. They are the talk of the playground, and everyone keeps asking me how she is – well, how would I know?

"It has been hard watching her when she is upset, there is nothing you can do to help. And it has been hard reading bad things that are said about her that just aren't true."

Her family say she isn't just loud and funny, but is also very sensitive and kind.

Josie is very close to her aunt, a relationship which has become closer in the last year. She said: "I have really missed her, she has been a real support to me since my partner died of cancer about a year ago. She has been great with my six-year-old daughter Lily, having her stay over at her place every night.

"She is very kind and generous, and she is always the one her friends turn to when they split up with their boyfriends. She's just that kind of person."

Her cousin, Jenna, 30, said: "She didn't go on there for the fame, she went on there for the life experience. She was bored of her job and thought she would give it a go."

Jenna will be at the final tonight with Amanda, Kay, Josh and another friend of Josie's.

They all say the £100,000 prize could change her life.

Mum Amanda said: "She has never had any money. Coming from a big family, you never have enough. I don't think she will come back here, she will travel and see the world."
