ISABELLE Warburton may have been a late arrival to the Big Brother house but she has certainly made a lasting impression.

The 21-year-old from Warrington is currently listed as the new favourite to win Big Brother 2017 after her odds were slashed. 

According to BET365, the contestant is the hot favourite at 2-1. 

Previous frontrunner and housemate Chanelle McCleary is now the second favourite to win at 3-1. 

Isabelle swapped the comfort of her home for the famous Channel 5 house at the Elstree studios in Hertfordshire last month.

But her antics have landed her in hot water after she was given a dressing down from Big Brother bosses after urinating in the hot tub and then her bed.

She also sacrificed £150 of the prize fund for a chat in the diary room with her family.

"We're so proud, we've had so many family and friends just keep on messaging saying how proud we should be," said Isabelle's mum over the phone.

She added: "We want you to enjoy every minute, we're still here. 

"We can't wait to see you. Just enjoy every second."

This year's series is presented by Emma Willis and Rylan Clark-Neal.

Isabelle follows in the footsteps of fellow Warrington contestant Lisa Appleton who appeared in the 2008 series of Big Brother.

Tune in at 10pm from Monday to Thursday and at 9pm on Friday to Sunday on Channel 5. 

The final will air on Friday, July 28, with Celebrity Big Brother set to start days later on August 1.
