Rihanna Weight Loss: Singer Says She Can’t Stop Dropping Pounds

Rihanna's body has always been central to her public image. The sexy singer loves rocking barely-there outfits, racy red-carpet looks and posting photos of her many bikinis. Naturally, with such a revealing wardrobe, it's easy to spot any changes to Ri's figure. And these days, it's the once-curvaceous singer's ever-shrinking waistline that's raising brows, AOL Music reports.

Ri was recently shot by the paparazzi in a midriff-baring outfit that revealed her protruding hip bones -- so when she called into 'On Air with Ryan Seacrest' this morning (March 15), her new figure came up in conversation. Ri had shed some pounds at the start of the new year by following the Hollywood-favored Five Factor Diet, personal trainer Harley Pasternak's nutrition plan of 5 mini-meals a day. But the diva revealed she's since strayed from the diet plan -- but continued to lose weight!

"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," she said. "So I really have no idea how I'm continuously losing weight," Rihanna admitted, acknowledging her thin frame.

"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!" Ri claimed. We're sure there are a few females out there who wouldn't mind having that problem!

Rihanna's claims follow comments from her father, Ronald Fenty, who said he thought his daughter was looking "fat" the last time he saw her and that he's glad she's losing weight.
