The singer described the follow-up to her current track 'Live It Up' as a "Christmassy" ballad.
She said: "I did say at the start that there's going to be a lot of variety when it comes to my music. It's not going to have a set genre, but it'll all have my twist on it. My next single is going to be a ballad.
"I think it's important for every artist to have that ballad that stands the test of time. I really feel like this ballad is one of those songs. I hope it touches people."
Asked if she was lining up a performance of the track during The X Factor live shows, she teased: "I think it's very possible. The third single will be out around that time."
Tulisa's latest single is currently at number 11 on iTunes.
The star was recently interviewed by a 7-year-old girl, who described Tulisa as her "favourite popstar".
