Britney Spears stepped out for coffee

One casualty in Britney Spears' new healthy life style? Her shrinking bust.

After a high profile stint in rehab last month, the singer kick-started a vigorous new exercise regime - including regular dance classes - to help her shed unwanted extra pounds.

But when Spears stepped out in LA in a lavender sundress with a plunging neckline , it was clear that her weight loss has also taken a toll on her formally buxom cleavage.

Wearing a hat and wig to cover her shaved head, the 25-year-old star grabbed a quick coffee while out and about in Beverly Hills, and paid a visit to a tanning salon.

Her shrinking frame has already sparked rumours that her weight loss could be due to cosmetic surgery .

Spears was treated at Promises rehab clinic in LA in March, after shaving off all her hair and attacking a paparazzi vehicle with an umbrella.

The single star - her divorce from Kevin Federline has been settled - has two children, Jayden James, 8 months and Sean Preston, 1.
