Ray J has been hospitalized seeking treatment for “exhaustion and jet lag” after Billboard Music Awards.

Ray J, 31, is also believed to have had a run-in with Whitney Houston’s family at the Billboard Awards on Sunday night which may have thrown him off course.

The singer and producer, who was dating Whitney Houston in the months before her death, was reportedly left “extremely upset” following a confrontation with Pat Houston.

Despite remaining for the star-studded event – and later hosting a party with Sophie Monk – it was the following morning that he was found.

TMZ report that someone ventured into Ray J’s hotel room on Monday morning and discovered he was “out of it” and couldn’t get out of bed.

He was said to have been “extremely disoriented” before whisked away by ambulance.

However, Ray J’s publicist is blaming the medical attention on the fact he’s been lacking a few nights of 40 winks recently.

The statement said: “Ray J has been in a Las Vegas area hospital since the early morning of Monday and will remain there for treatment for exhaustion and jet lag.

“Ray J was in Las Vegas hosting a launch party (with Sophie) for the product he is endorsing, Prince Reigns Hair Serum, and to attend the Billboard Music Awards.

“Ray J had just returned to the US from a quick 32-hour round trip from China where he performed a concert and had meetings regarding a new business.

“Upon landing, he immediately drove four hours to Las Vegas for the two events.”

Ray J has not tweeted since last Friday, when he told fans: “I’m in the Las Vegas of HongKong (sic).”
