The N-Dubz singer revealed that they work well together despite the breakdown of their relationship, as they understand what each other's musical tastes are.
Asked if she would be up for a future collaboration with Fazer, Tulisa told Capital FM: "Yeah definitely. If Fazer was ever to make a record for me it would be a smash.
"Just because he obviously knows me so well and he knows what I want and what I look for in a record."
Fazer - real name Richard Rawson - co-produced Tulisa's debut single 'Young', which will be released in the UK on May 6.
Speaking about selecting the track as her first solo single, Tulisa explained: "It was one of those records that when I heard it I went, 'I have to have this record, I have to have it'. It just represents everything that I'm about."
Tulisa recently confirmed that she will perform 'Young' live on Britain's Got Talent next month.
Her debut album is expected to be released in November.
