Recently reunited real-life couple Rihanna and Chris Brown are reportedly working on a new single, which is also their fourth collaboration. The rumors spread after the two were spotted sneaking out of a music studio last week, and was later confirmed by a representative. When Rihanna was asked about their rekindled relationship, she refused to answer and said it's "nobody's business". Interestingly, that's also the title of their new single.
