While it’s absolutely insane to label Rihanna as overweight at any point in her career, the ‘Where Have You Been’ songstress was noticeably thicker (her dad even approached her about it) when she paraded around in a bikini on Kadooment Day in Barbados last August. As of late, Rihanna has been showing off a much thinner and toned figure, and it has a lot of people scratching their heads as to what her dieting secret is.

Yesterday, during an interview with Ryan Seacrest on his KIIS-FM radio program, Rihanna dished on her weight loss, which isn’t really a priority for the singer — in fact, it downright bothers her that she’s so skinny! ”It’s actually pretty annoying. Now, I don’t have a butt, no boobs — already had no boobs — so annoying,” she told Seacrest.

“It’s difficult to have any kind of routine when your schedule is that crazy,” Rihanna continued. “So I really have no idea how I’m continuously losing weight.” She also went on to explain that it isn’t working out or other factors that are leading to her weight loss, and it certainly isn’t her diet. “So annoying. I’m eating everything — people think I’m not eating — and I’m eating McDonald’s at 3AM type and it’s an issue. I’m eating ice cream.”

Whatever she’s doing, it seems to be working, because RiRi is looking hotter than ever!

During the interview, Rihanna also dished on working with Chris Brown on her ‘Birthday Cake’ reemix, of which she said, “I thought about rappers, and I’ve done that so many times, and the hottest R&B artist out right now is Chris Brown… There shouldn’t be a divide. It’s music, and it’s innocent.”
