Busta Rhymes exchanges vocals with Carey on the chorus, though he originally wanted an R&B vocalist to sing the male part. He recalled on the YouTube documentary Busta Rhymes, Mariah Carey - DIVINE: The 18 Year Anniversary Celebration
that after receiving Rock's instrumentation and recording some dummy vocals, he reached out to Carey, who told the rapper to send her the demo. Busta explained that he sang the reference vocal on the hook to give her an idea of what he thought she should be doing, but Carey "insisted" he was the right man for the job.
"Yes, Busta was singing and I remember going like, 'Do you want me to sing this part over? Or... like 'is he keeping that part?'" she recalled. "Because at that time, rappers weren't really doing the singing thing, but I loved it."
