The Sugababes star, who is currently working on solo material in the recording studio with producer Pete Kirtley, previously described one of her songs as "ridiculous!!! In a good way!"
However, Berrabah has now strongly indicated that her debut single is named 'Rebel', after she started to use the word as a Twitter hashtag when talking about her solo project.
Writing about her new official Facebook page, she tweeted: "More pics 2 come soon people!! Don't 4get 2 check out my official Facebook site!! Love u guys! #REBEL!x"
The star then continued to respond to and retweet fans using the 'Rebel' hashtag.
An official confirmation on the release of the new track has yet to be issued, but Berrabah recently suggested that it would be soon.
Fellow Sugababes member Heidi Range has teased that she has also considered recording a solo album while the girl group take time off to pursue their own individual projects.
