The former Apprentice candidate and US reality star Austin have been firm friends since day one and even though they've had their fair share of rows, their bond has remained steady.
Speaking on the last night in the Big Brother house, James told his housemates: "18 months ago, for me to sit here and think that I would be in this house with celebrities... I had never seen a celebrity or met a celebrity before I walked down them stairs.
"But all of us in here have had a journey, had our tough times. That is who we are."
He then turned to Austin and said: "My mate, my pal, I am so grateful that you were here in this house because I am a loner. I am loner and in life I have spent a lot of time on my own and not had many friends and I have always struggled to let people to get close to me through my past, and you know I've always turned to people to lean on them and to have someone around me, and you were that guy, man."
Austin and James face Sherrie Hewson, Bobby Davro, Chloe-Jasmine and Stevi Ritchie, and Natasha Hamilton in the final.
CBB's finale airs at 9pm on Channel 5.
