'Wild Heart' hitmakers The Vamps have revealed that collaborating with Demi Lovato on their latest single has been a massive boost in terms of getting them more international exposure and credibility. 

Speaking to MTV News, the band's frontman Brad Simpson explained that he thinks having her vocals on 'Somebody To You' is a great help to their career and they're all really excited that she worked with them:

"I think it’s definitely helped us. To have such a superstar on the track is amazing. I think it’ll help us hopefully in America as well to reach new audiences."

"And hopefully, in some kind of way, we’ve helped her as well to open her up to our fans, who probably will have heard of her, but will now get to experience the amazing Demi Lovato."
