The singer has teamed up with US rapper Tyga for 'Live It Up', which is her second solo single and is scheduled to be released on September 10.
The track was written and produced with the help of Rico Love, who has previously penned tracks for Usher, Beyoncé and Chris Brown.
"Basically, with this single there is no aim at all to get a number one or storm the charts," Tulisa told Capital FM.
"This is now me going back to me and trying to define myself as an artist because I knew I wanted a number one hit as my first release. I got that with 'Young', so I went even more urban with this second single."
She added: "I don't expect it to even possibly get top ten it's that urban, but you never know.
"The fanbase could pull through, the N-Dubletts could pull through, and it is a smash but it's an urban smash and I know that in the UK these days it is a lot tougher with urban music."
'Live It Up' is the second track to be lifted from Tulisa's debut solo album, which is due out later this year.
