Nicole Richie has always been flat chested, but after getting her breasts done over the summer, that has changed. She didn't go overboard, she just had more of a boost and she fills out her clothes better.

After she had her first child, Harlow, and was breast feeding, Nicole said she really didn't like having big boobs. A source says, "The pregnancies took a toll. She said breast-feeding killed what boobs she did have! In the past, Nicole had said to pals that she wanted a lift, but her friends "never thought she was serious."

Yes, pregnancy and breast feeding can take a toll on your boobs and Nicole didn't have much that she's was workin' with before she got pregnant. I like her new set! The first three photos of Nicole and her new boobies were taken earlier this month, while the others show a flatter pre-implant Nicole.
