BIG Britney Spears pregnant may 05Britney Spears - just before the hospital dashPregnant Britney Spears had another hospital dash drama after complaining of stomach pains.

The 23-year-old pop star was looking after husband Kevin Federline's little daughter when she had to be rushed to hospital for emergency tests.

She had to interrupt her husband's recording session in Hollywood to raise the alarm, before Kevin drove her to nearby UCLA hospital in Santa Monica.

The Sun reports a source as saying: "Britney had been taking it easy on doctors' advice.

"She was playing with Kori on the grass outside the studios. She started to look unwell and was holding her stomach.

"She called Kevin out of the studio to tell him she was getting worse."

However, after 90 minutes of extensive tests, doctors gave her the all-clear but ordered the star to do as little as possible.

All this comes just weeks after it was feared Britney was having a miscarriage - it later emerged that she had suffered premature separation of the placenta from the uterus.
