The US reality star shocked housemates when he launched into a foul-mouthed rant against Janice, which included saying: "You f**king embarrassment of a mother, you should be ashamed. You stupid c**t."
Speaking on Thursday night's live finale, Austin said: "I was bang out of order with what I said. I'm not the kind of person who sits down and analyses my childhood and goes back, but after doing that, I felt like I had to psycho analyse myself. I have a lot of anger issues with my mum, my brother passing. It's been a difficult two and a half years.
"Janice didn't deserve that and I hope I expressed my regrets to everyone as it was embarrassing for me and I hope it never happens again. If I can go three and a half weeks in a house and have one outburst I'm embarrassed at, I think that's good."
Austin said of Janice: "She's a very strong alpha female. I'm a very strong gay guy. Sometimes those things just don't compute. I think we have a lot more similarities than we do differences. 100 per cent... I will say, every time I was rude to her I was provoked. I never went out looking for a fight with her.
"After every conversation I had with Janice, people would tell me I went about it the wrong way but what I said was right."
