Rihanna has spoken about her new duet with Chris Brown. The singer has teamed up with her former boyfriend on a new song titled 'Nobody's Business', which features on her forthcoming album ‘Unapologetic’."'Nobody's Business' is basically the way I look at everything regarding my personal life," Rihanna explained during an interview on Facebook Live."You know, even though you have to witness it as being documented at every second, it still is mine... this is mine at this point."When it gets to my music and stuff like that, I will give and I'll give and I'll give, and I feel like I just need to keep a little bit for me that I get to decide."Bravo's Andy Cohen - who hosted the talk - then suggested that the reason the public speculate about her personal life is because she records songs like 'Nobody's Business', inviting fans to interpret the lyrics.Rihanna responded: "Well, I'm not putting it out there as much as it is just there. You know, I can't run away from that. If I had it my way, it really would be nobody's business, but I can't escape that!"Rihanna's seventh studio album ‘Unapologetic’ will be released worldwide on November 19. The Sun
