Ray J Rushed to Whitney Houston's Hotel, Turned Away by Cops

Ray J was home when he got the word Whitney Houston had died last night, but he was turned away by law enforcement at the hotel after he raced over to try and see her ... TMZ has learned.

Sources close to Ray J tell TMZ he went straight to the Beverly Hilton to try and see Houston as soon as he got the call that she had passed away. He had not been with Houston at all that day or the night before.

We're told when he arrived, law enforcement turned him away just as they did Bobbi Kristina. Ray J can be seen in the photo above, moments after, outside Whitney's room on the 4th floor.
