The pop singer and West End star said that the band are more "mature" then when they were first touring, claiming that they will be less outrageous on the road.
When asked about bandmate Lee Ryan's recent revelations about the group enjoying threesomes with fans, James, said: "Lee always speaks out. You never know what's going to come out of his mouth. It was quoted before and it wasn't anything new. He just wanted to bring it back up again now.
"I called him and said, 'Lee!', and he said, 'I'm sorry brother, the record company told me to spice up the interview!'. And I said, 'that's great, but why bring me into it!' High fiving with the spit... oh God Lee!"
Speaking about the possibility of recreating the sex act, he said: "Probably not, no. No. I'd like to think we're a little bit more mature now. I'd like to think we have grown up a bit and won't be doing that... so much."
He added: "But I am quite excited about getting back together with the lads, going around causing mischief. All the red tops will be loving that we are getting back, because last time with Blue there were stories every day about something. Whether it was Lee shagging an alien, or whatever. It does make you think, what's going to happen this time around?!"
James is a judge on new reality series Don't Stop Believing, which starts on Sunday at 7pm on Five.
