London: Singer James Arthur apologised for his behaviour in recent times and thanked those who stood by him when the going was tough.
Arthur, the 2012 winner of "The X Factor", experienced a fall in his fame after he made homophobic comments on rapper Micky Worthless.
The 25-year-old performed at the `The X Factor` episode Sunday and took the opportunity to come clean, reports dailymail.co.uk.
"It`s been an amazing year for me, incredible highs paired with incredible lows. I`ve made some very silly mistakes but I just want to thank everyone who stuck by me through this difficult time," said James.
"Above all, I just want to say sorry for abusing my position as an `X Factor` winner because I owe this show everything," he added.
