Ray J has been released from hospital.

The 31-year-old singer was admitted to a medical facility in Las Vegas on Monday suffering from exhaustion and jet lag but has now been given the all-clear following extensive tests.

"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," his representative told US Weekly.
