Rihanna Explains Why She Wanted Chris Brown On ‘Birthday Cake’ + How She Accidentally Lost Her Booty

Thursday morning, singer (and now actress) Rihanna called into Ryan Seacrest. Peep a few excerpts.

On Collaborating With Chris Brown:

“The first song that came about was ‘Birthday Cake.’ I mean we ended up recording them at the same time and executing them together, but I reached out to him about doing ‘Birthday Cake’ because that’s the only person that really–it made sense to do the record. Just as a musician despite everything else that was going to be the person. You know I thought about rappers, and I’ve done that so many times, and the hottest R&B artist out right now is Chris Brown. So I wanted him on the track, and then in turn he was like ‘Why don’t you do the remix to my track?’ and it was a trade off. We did two records. One for my fans. One for his fans, and that way our fans can come together. There shouldn’t be a divide. You know? It’s music, and it’s innocent.”

On losing her boobs and booty via The Five Factor Diet:

“The Five Factor Diet has gone straight out the window ever since I went on tour. I mean, It’s difficult to have any kind of routine when your schedule is that crazy. So I really have no idea how I’m continuously losing weight. It’s actually pretty annoying, because now I don’t have a butt, and I have no boobs. I already had no boobs to start with. So annoying! and I’m eating everything!”

On why she went blonde:

“Yes, I am….I really want to go black, and I was kind of in a natural color so it was easier to go blonde first, because black is such a harsh color to come back from. So I wanted to try it out to see if I liked it, and now I really am a little attached to it. I keep going lighter and lighter. So I’ll just have some fun with it, and when I get bored I’ll just….black is an easy change from here.”

On her line with Armani:

“a small collection that I do for Armani. It’s a collaboration, and it’s like 7-10 pieces. Apparel and accessories and we’ve done the fall collection already, and it was very, very successful and now the spring collection is about to drop. After that I’m really pursuing a fashion line of my own. I want to design. This is also a road that I want to earn it. So I’m working with designers. Designers that I respect, and [fashion] companies that I respect. I want people to really trust me before I just say ‘Buy it, because it’s mine.’”
