Speaking to Now magazine, Dappy explained how the group are n longer talking after so much "drama" between them over the past 12 months.
Recent weeks alone have seen Tulisa and Fazer end their relationship, with claims that Fazer cheated on Tulisa last November.
Talking about his own relationship with the feisty singer, Dappy said this week: “It's upsetting. I'd love to be able to hold her, cuddle her and give her a kiss again."
But he insisted: "It wasn't jealousy. We just had to do our own thing. She'd boss me in her way and I wouldn't like it. Poor Fazer was stuck in the middle."
“We both wanted to be the boss. We're both very stubborn. We both weren't having it. We were killing each other every day. She's said she was sick of all the drama. It's easier for her not to talk to me because I'm a bag of stress. But she knows I love her to death. I'd do anything if she ever needs me."
And Dappy claimed that Tulisa's relationship with Fazer made him feel uncomfortable.
He said: "Listen, with them two being a couple and me finding out about it properly, it didn't feel like N-Dubz anymore. I'll tell that to the world.
“I was glad that my best friend was the one with my cousin. But at the same time it felt like it was Tulisa and Fazer with Dappy. It didn't feel like N-Dubz.”
But before N-Dubz fans give up hope of a reunion, Dappy suggested that they would definitely reunite for another album soon!
