London, Mar 3 : Cheryl Cole has figured out the best way to lash out at footballer hubby Ashley Cole - a four-letter rant in a new song.
The Girls Aloud singer has been in Los Angeles to shoot a new documentary for ITV2 called 'The Passions Of Girls Aloud,' which is based around each band member achieving something they have always wanted to do, other than pop music.
The singer reveals her passion for street dancing in her section of the four-part series.
Cheryl has also been asked to add vocals to the documentary and she has a barbed line for England and Chelsea defender Ashley in one song.
She has been recording the new single with Black Eyed Peas star Will.i.am and part of her vocals go: "You've been a f****** jerk!" "For her documentary, Cheryl was originally just meant to be part of the dance troupe for Will.i.am's song - but he asked her to do backing vocals," The Sun quoted a source, as saying.
"The track is called Heartbreaker - all about men treating their partners like dirt and cheating on them.
"Will sings a line admitting he has cheated and Cheryl sings back that he has been an effing jerk.
"Recording the vocal was quite cathartic for her. She used it to let off some steam.
"When she sings the line, she really means it - no question," the source added.
