The Live While We're Young singer and Peazer - who met on the 2010 series of The X Factorwhere she worked as a backing dancer - called time on their romance last month.
Payne has now addressed their break up, telling Now magazine: "I've been trying to deal with it in private.
"I'm not so much worried about me - whatever happens I'll live and deal with it. I'm more concerned about Danielle because I don't want people harassing her for any reason."
He added: "Obviously she's got a lot on her mind without people saying things on the internet or going to her doorstep.
"She doesn't need that right now... I've asked for people to stay away from her as much as possible so she can deal with things."
The 18-year old also went on to slam those who targeted Peazer online during their relationship, telling the publication: "Twitter twists things a bit. People have a false sense of confidence behind a keyboard.
"Some of the things they say I just can't believe. I think, 'How can you say that? You wouldn't be able to say that to someone on the street, so why say it now?' But it's one of those things."
