In an interview with Akshay Bhansali of MTV News, Guetta revealed that he did not know Hudson before collaborating on the song, saying, "I had heard her voice [before] and I fell in love with it. It's a difficult song. You need a really big voice to be able to perform that song. I was like, 'Whoa!' She obviously has an amazing voice, and I think it was a really interesting exercise for her and for me." Guetta further explained that when he collaborates with artists, he likes to "take them out of their boxes", and creating a dance record with Hudson was "really exciting" for him. On working with Hudson, he said, "She is beautiful in every way: as a person, as a singer, as a human being. She delivered [the song] like crazy."
