The 'X Factor' winner's former mentor said she that despite his recent controversies she is "there for him".
She told Digital Spy: "I don't read the press, I know who he is as a person, I know his heart.
James Arthur and Nicole Scherzinger
James recently apologised live on the 'X Factor' for his use of homophobic language in a rap and recent outbursts on social media, which included a spat with former pal Lucy Spraggan.
He told host Dermot O'Leary: "It's been an amazing year for me. There's been some amazing highs but also some lows.
"I've made some very silly mistakes. I want to thank 'The X Factor' for giving me this opportunity.
"I want to say sorry for abusing my position as an X Factor winner because I owe everything to this thing."
Nicole and Alan Carr
Meanwhile, Nicole presented Alan Carr with the Best Comedy Entertainment Personality award at last night's British Comedy Awards.
Her appearance at the Awards comes ahead of the 'X Factor' final on Saturday, where - unlike last year - she will have no acts left to mentor through the showdown.
