The 31-year-old reality star had arrived in Vegas on Sunday for the Billboard Music Awards after a 32-hour round trip to China.

The singer's rep released the following statement:

    "Ray J has been released from the hospital in Las Vegas and is back home in Los Angeles following an extensive battery of tests to make sure that he did not have a blood clot in his lungs which is potentially a deadly condition that can occur following a long haul plane flight."

Just last year, rapper Heavy D died from a blood clot in his lungs.
