Rihanna has slimmed down recently but she does not seem too happy about losing some of her curves.
The 24-year-old singer, who is recording her new album and recently starred in the action film "Battleship," told Us Weekly, "I'm a size zero and I'm not happy about it!"
She later added, "I went way too far. I prefer myself a bit chunkier. I want my old butt back."
The singer is currently working on her seventh studio album and was hospitalized after attending the Met Ball in May for fatigue.
The statement is a far cry from the positive body image she had in March when she told Vogue magazine, "I just feel sexy. For the first time, I don't want to get rid of the curves. I just want to tone it up. My body is comfortable, and it's not unhealthy, so I'm going to rock with it."
Rihanna, whose acting debut in "Battleship" performed poorly at the box office, said she would like to do more films in the future before going back on tour.
"I want to do two more [movies] before touring again next year," Rihanna told the magazine. "My schedule is crazy!"
The singer recently filmed a role in the movie "The End of the World," where she and other celebrities like Jonah Hill, Emma Watson and James Franco play themselves at a party at Franco's house. During the festivities, the celebrities are faced with apocalypse.
