Rihanna wants a bigger butt.

The 25-year-old singer is known for flaunting her enviable curves in skimpy outfits but she admits even she has body hangups, just like every woman, and she particularly wishes she had a peachier derrière.

Speaking to E! news, she said: ''I do pick on my body. It's a thing that women do. We walk in front of the mirror and we look at our butt. Is it getting bigger today? Ew. It's still flat.''

Meanwhile, the 'Stay' hitmaker previously admitted she was jealous of Beyonce's good looks and stunning physique, but in 30 years time she wants to be confident with her own body.

She said previously: ''I want to be skinny. I want to be fierce. I hope my t*ts are still sitting up. Nothing else will matter at that point.''

The brunette beauty also admitted that she's learnt to accept her curves because nobody is happy in their own skin.

She said last year: ''I mean you get comfortable with the fact that that's your body and that is what it is - that I had to learn. (Some days) I'm like, 'OK, whatever, I feel fat today,' but what can you really do about it? You have to just accept your body.

''You may not love it all the way, but you just have to be comfortable with it, comfortable with knowing that that's your body. You just want something else that someone else has, but that doesn't mean what you have isn't beautiful, because people always want what you have, and you always want what they have - no one is ever 100 per cent like, 'Yes, I'm the bomb dot com - from head to toe!'''
