LATEST: Pop star Britney Spears has rubbished speculation she is expecting a second child, just seven months after giving birth to baby Sean Preston.

The OOPS!... I DID IT AGAIN singer was rushed to hospital last week (ends24FEB06) fuelling rumours she was suffering from severe morning sickness.

A source tells gossip site The Scoop, "She was throwing up and had stomach cramps. She's pregnant."

But Spears' rep has slammed the story, insisting, "It's not true. She's not pregnant."

Earlier this month (FEB06), reports claimed the star had announced her second pregnancy at Malibu, California store Shabby Chic, declaring, "That's right, number two," while proudly rubbing her rounded belly.
