I can buy it:

Britney Spears has denied that she is pregnant with her third child and says that her bloated tummy is simply down to new medication she is taking.

The singer spoke out after pictures after pictures published this week showed the star smoking a cigarette with a suspiciously bloated stomach.

A source close to the family says that Britney has been struggling with her weight ever since she had her second son Jayden James, 20 months, and the medication has not helped.

The pop star has been back in training in preparation for a comeback, spending plenty of time on the treadmill - but despite all the effort, she is failing to regain the svelte figure which made her famous.

Her tummy bulge seems to come and go, and go and come back, so I didn’t think she was, although it certainly did look that way.

I hope the recent rash of speculation and photos don’t make her think about stopping her meds.  A little bit of weight is a small price to pay for good mental health, and Britney looks and is acting healthier than she has in well over a year.

Besides, I don’t think she is one of those women who can slim down to pre-children size.  Somebody like Posh Spice can, perhaps; but then, all she eats is soybeans and seaweed, and look how unhappy she appears all the time.   A few curves in all the right places look good on Brit…if she’ll just stay away from spangly knickers.  If she doesn’t try to dress like she did as a teenage pop star, and makes an attempt to dress more for her body now, she could totally create new trends.  You go, girl!
