Hilary Duff Turned Down Charli XCX's "Boom Clap" and Didn't Even Know It

Last month, Charli XCX revealed in an interview with Popjustice that she originally offered her hit single "Boom Clap" to Hilary Duff but her team apparently turned it down because it was "not cool enough" for her.

When addressing the subject with the magazine, the "So Yesterday" singer said she had no idea she was even offered the track in the first place and that it's her current favorite song.

“I didn’t know that I had an option to have it,” Hilary says. “It’s my favorite song on the radio right now.”

“I remember there was talk about my label trying to get us to write together and it was in New York and I was flying home so I didn’t have time to have a session with her. I am literally obsessed with that song and I didn’t know that it was an option for me.”

Hilary Duff will release her new single "Chasing The Sun" on July 29th via Island Records.
