The singer told Digital Spy that she told her label to sound out the ‘Wuthering Heights’ singer about a collaboration, but it was unable to track her down.
Roberts explained that Bush (pictured below) proved to be a key influence during the making of ‘Cinderella Eyes’, which is due out in the autumn.
“I don’t think anyone knows where she is to be honest. I kept asking and hinting and eventually begging my label for the whole year I was making the album,” Roberts commented.
“I was influenced by a lot of her music and was desperate to work with her.”
She recently insisted that the album is a true representation of her musical tastes, telling NME that “people can sniff out a faker”.
