According to the website, “Ray J was extremely upset after his confrontation with Whitney Houston’s family — notably Pat Houston — during the awards ceremony.  On Monday morning, someone went into Ray J’s hotel room and realized the singer was ‘out of it’ and couldn’t get out of bed.

“We’re told Ray J was extremely disoriented and was immediately taken to the hospital by ambulance.

“As for what happened … it’s looking like a combo of exhaustion and stress.  Ray J had just returned from a quick, 32-hour round trip to China and when he landed he immediately drove 4 hours to Las Vegas for the awards show.”

At press time, Ray J was still in the hospital, according to TMZ.  No word on when he’ll be released.
