The 25-year-old singer is still very much in touch with his former 'X Factor' mentor after she helped him to win the competition last year, and he can't wait for the music they have recorded together to be released, insisting it is ''certainly good''.
He exclusively told BANG Showbiz: ''I speak to her all the time. She's a really good friend of mine.
''We have made some music together and it's certainly good, but I'm not sure when that will come out. We'll see.
''Whether it pops up on her next album or my next album or just in general who knows, but I think you will hear something from me and Nicole at some point.''
Since shooting to fame on the show James has been romantically linked to several stunners including Page 3 model Lacey Banghard and most recently adult channel star Lori Buckby, and he finds it ''funny'' being linked with so many beauties.
He added: ''I just find it funny, it's just another person I've been linked to. I think I've met that girl before but I'm in now way in a relationship with her.''
Many ticket-holders couldn't get into the O2 Arena show on Tuesday night (September 19th) because they didn't bring photo ID to match their booking.
An album re-release, a new song and a documentary mark the singer's legacy this year.
The actor plays the titular hero in the forthcoming adaptation.
