Britney Spears' Stomach Fuels Pregnancy Speculation 5/14/08

Britney Spears has fuelled speculation she is pregnant - after she was photographed on a cigarette break looking more rotund than usual.

The star, 26, was photographed during a day out with sons Sean Preston, two, and Jayden James, one, in Beverly Hills, and her shapely form has sparked claims she is expecting her third child.

Dressed in purple tracksuit bottoms, a plunging Ed Hardy t-shirt and a hooded top, Spears' midriff looked much larger than her previously toned stomach. Spears' younger sibling, 17-year-old Jamie Lynn, is currently pregnant with her first child.
