It looks like a hard time for Britney Spears. The pop princess of U.S and worldwide, was rushed to the hospital, accusing stomach aches.

A witness to the incident said that "She was playing with Kori 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."

After one hour and a half of tests, doctors said everything's ok, but she has to rest for a while and take it easy with her work and life.

It appears Britney's pregnancy is troublesome. She had to go several times in the emergency room, accusing different aches, everything culminating last week, when doctors feared she will have a miscarriage.

The pop star went to emergency ward of the Sacred Heart Hospital in Destin, Florida with her husband Kevin Federline and a bodyguard.

There, doctors have found a premature separation of her placenta from her uterus but determined there was no danger to her baby.
Spears was discharged from the hospital after two days of observation.

Britney Spears, 24 years, known worldwide as the pop princess, remained pregnant with Kevin 4 months ago. Rumors have it that Spears and Federline were about to break up and their life-and-death hospital dash occurred during a holiday aimed at saving their marriage.

A few weeks ago, a Spears spokesperson confirmed they had gone away to "sort out their personal problems", heading to a condominium Spears owns at Destin, Florida.
