Britney Spears strutting her new curves with an especially increasing waistline continue to fuel rumors that pop singer is pregnant.

Though Britney Spears denied the rumors, a New York Post columnist has claimed sources insist "blooming Britney and hubby Kevin Federline are very definitely expecting".

Two celebrity magazines, including US Weekly, have also claimed Britney Spears, 23, is pregnant, citing anonymous sources.

A couple of months ago Britney was spotted in a baby clothing store in Los Angeles, where she enthusiastically browsed the tiny dresses for newborns. According to other sources, Britney was seen buying maternity swimwear.

And, under the headline "Baby on Board", US Weekly said she had been spotted munching through a beef sandwich, but avoiding coffee and cigarettes. Britney also became fond of home cooking instead of fast-food.
