The former N-Dubz star - who previously dated his bandmate Tulisa Contostavlos - also told The Sun that he will keep details of his private life to himself in the future.
"I would never get into another relationship where it's so open to the public eye," he said. "When everyone else has an influence on it, when does it leave time for you two?
"No, man. Everyone's got an opinion on this and that. I'll never tell anyone who I'm in a relationship with next."
Fazer revealed that he and Contostavlos - whom he refers to as "T" - are still on good terms, but admitted he missed having her and Dappy's company in the studio when recording.
"I miss the magic in the studio, the arguments and performing, but I'm having a lot of fun," he said.
"We're all so busy but we keep in close contact over the phone and texts. Next year we'll have three solo projects coming out then hopefully mid-2014 we can come back and do another N-Dubz album. I'd be over the moon."
Fazer, who recently revealed that he was asked to produce music for Rihanna, will release his debut album later this year.
'Killer', the first single from the as-yet untitled LP, is out now.
