The American reality television star admitted he was "really hurt" by the former 'Apprentice' contestant after he said the pair barely knew each other.

In last night's (17.09.15) episode, Austin said: "I've spent more time with you than anyone in your life. I can't say anyone else I have spent 500 hours with. I think I know you pretty well and you know me pretty well."

To which James replies: "I don't know you at all. You don't know me at all."

Austin goes on to tell James, "that was really f***ed up. I have never spent 500 hours with my friends consistently for three weeks."

And the 27-year-old entrepreneur hit back adding: "I have been friends with some people since I was 4-years-old."

The argument only worsened when Austin admitted he had told James things he hadn't shared with anyone else.

He said: "That really hurt me. I shared things with you that I haven't shared with anyone. I've confided in the person that you are and then you say I don't really know you and you don't really know me. That's really f***ed up. I haven't told the other people [these personal things]."

In last night's (17.09.15) episode, the contestants also learned they will all be up for eviction as the final looms.
