American Idol favorite David Cook was sent to the hospital immediately following last nights show because of heart palpitations and high blood pressure according to TMZ.

After the show, Cook was driven to the hospital (not by ambulance) and treated by a private doctor to keep everything on the down low. The doctor gave Cook medication to bring his blood pressure down and he will monitored again Tuesday.

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.

Our prayers are with David and his brother both during  these trying and  exciting times.
