Keisha Buchanan's new track has been leaked online.
The former Sugababes singer - who left the group in September last year amid rumours of tension with bandmates Heidi Range and Amelle Berrabah - has had new tune 'Fearless' posted on the MySpace page of music producer Charlie Holmes.
The lyrics to the track are said to include: "I'm fearless, I'm not afraid to be alone/It's over why?/Because you did something wrong."
While it is not yet known whether the track will feature on Keisha's debut album - which she has been working on since she was reportedly ousted from the group - the lyrics have prompted speculation that the new material will cover the 25-year-old singer's spat with her former bandmates.
The 'Freak Like Me' hitmaker recently revealed her solo record will be about "being a Survivor" and is due for release later on in 2010.
She said: "People may read things into the tracks when they come out but they are not about one specific person or the Sugababes. I wish them all the best."
However, the current line-up - Heidi, Amelle and Keisha's replacement Jade Ewen - insist her solo efforts are no "competition" to them.
Jade explained: "Keisha is a solo artist and we're a group so we're not in competition with each other at all. That would be ridiculous - I've never even met her."
