Ray J Almost Physically Removed From Billboard Awards

Pat Houston's blood was boiling because she, Bobbi Kristina and other family members were seated next to Ray J, the person Pat believes was a very bad influence on Whitney. Minutes before the tribute to Whitney, Pat asked her security to remove Ray J from his seat, but he refused to budge.

Our sources say ... Pat's security summoned hotel security, along with several uniformed officers to physically remove Ray J.

Just before push was about to come to shove, security warned Pat that things would likely get physical and it would almost certainly be caught on video, just as Whitney was about to be honored. Sources say Pat then grudgingly recanted and Ray J kept his seat.
