Tulisa teases 'Live It Up' video - watch
The promo for 'Live It Up' will debut in full on Monday, ahead of the single's official release on September 10.
The X Factor judge is seen dancing on the beach in the video, which was filmed in Hawaii.
'Live It Up', which features US rapper Tyga, is Tulisa's second solo single after 'Young' topped the charts in April this year.
"Basically, with this single there is no aim at all to get a number one or storm the charts," she said of the track.
"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."
Tulisa recently brushed off claims that she doesn't get on with new X Factor judge Nicole Scherzinger.
