Britney’s Breasts under shrinking transformation

It seems that Britney Spears’ post rehab vigorous exercise regime has had a little extra effect on her breasts.

It was clear that Spears’ formally buxom cleavage had reduced, after she was spotted in a lavender sundress with a plunging neckline.

A source told the American magazine Star that with Britney already eyeing the revival of her flagging career, the first thing she wants to get back in shape is her figure.

"Britney wants to look better than she ever has in her life. She has a plan and has already started working on it.She is a size 6 (UK size 10) and wants to be a size 2 (UK size 6) when she is done in three months," the Daily Mail quoted the source, as telling Star.

However, her smaller frame has already fuelled rumours that her weight loss could be due to cosmetic surgery.

The singer was spotted a week ago emerging from a cosmetic surgery clinic showing signs of losing some of the weight she has put on due to her back to back pregnancies.
