After a number of controversies including arguing with Frankie Boyle and making a homophobic slur, James decided a second apology was needed.
He said: "It's been an amazing year for me. There's been incredible highs paired with some terrible lows. I've made a few very silly mistakes. I just want to thank all the people who are still supporting me and especially The X Factor for giving me the opportunity to do my dream job.
"Above all, I'd like to say sorry for abusing my position as an X Factor winner, because I owe everything to this thing."
Let's hope there isn't another spat with another celebrity over Twitter after this one, shall we?
