Lacey Schwimmer is rocking new size D [expletive], and she’s happy about her enhanced look.

The Dancing with the Stars pro, who was an ardent supporter and defender of her partner Chaz Bono, has gone from an athletic build and a size B cup to a size D cup.

“Lacey’s told friends she got a boob job. She'd wanted one for a while so she went ahead and did it," a source close to the dancer told Us magazine about her curvy shape.

First snapped over the summer in a bikini with her new [expletive], the 23-year-old beauty is thrilled with her body now.

A source said, “She loves the results and she's proud of her new shape."
