Vocal powerhouse Jessie J has revealed that a new song she wrote was selected for the soundtrack to the upcoming sequel, 'Kick-Ass 2'.

During an extensive Twitter question and answer session on July 6, the 'Price Tag' beauty was asked by one of her followers if there was any truth in the reports that suggest she has contributed a cut to the movie's soundtrack, to which she excitedly replied:

"YES this is true! Finally something that's trueeeee! It's called 'Hero'."

Jessie J also opened up about her forthcoming new album, which was originally rumoured to be titled 'Gold', and confessed that it features songs called 'Breathe' and 'Square One', but it will not include a collaboration with singer-songwriter Ed Sheeran.
