The gorgeous singer explained: “I guess my butt is natural. But I go through stages like every woman. I like being curvy but sometimes I get curvy in the wrong places.”

“After New Year I do stairs - they are the best thing for butt cheeks. Every January I'll start working out. I'll do that for three months and then stop again!"

And B also revealed she hates being put in ‘Most Sexy’ lists. She said: “Some people think one thing is beautiful, some think another is. When people say that I am 'most beautiful' or 'most sexy', it bothers me.

“I like fashion and I like to look good. I like to try at least, but everyone has their own opinion.”
