"American Idol" contestant David Cook was rushed to the hospital last night after experiencing heart palpitations and high blood pressure. Released a few hours later, the white rocker's condition was still not resolved.
As first reported by TMZ, Cook was not feeling well during the day and his condition worsened after his performance. Cook was examined by show medics who determined his blood pressure was "far too high." Cook was urged to leave but wanted to wait it out.
An "A.I." exec tells us Cook has been completely stressed out because his brother, who has been sick with cancer, had a setback within the last week. Earlier in the season, just before a performance, David collapsed and said he could not go on -- though he pulled it together at the last minute.
