Ray J is resting.
A rep for the R&B artist tells E! News the singer was taken to a Las Vegas-area hospital on Monday and "will remain there for treatment for exhaustion and jet lag."
On Sunday, Ray J attended the Billboard Music Awards in Sin City and, later that evening, hosted a launch party at the Rio Hotel & Casino for Prince Reigns, a hair serum product he is endorsing.
According to his rep, Ray J had just returned to the U.S. following a "quick 32-hour round trip from China" and upon landing immediately drove four hours to Las Vegas.
Yep. Sounds like the guy could definitely use a little shut-eye.
