Quote from People Magazine:
The singer said that the surgery took place in October last year in Houston. The reason she did it, according to Jen Garcia from People, is not because she wants to compete with her former bandmate Beyonce Knowles but because one of the things, is to fit into designer outfits. She, reportedly has wanted this operation since she was 17. On choosing what size she wants, the magazine quoted her as saying, “…simply went from an A-cup to a B-cup… I didn’t want double Ds and be a little bitty size 2, that would look nuts!”.
