Michael Jackson's brother Randy has been hospitalized with chest pains.

Randy Jackson was taken to the Huntington Memorial Hospital in Pasadena, California on Tuesday as a precautionary measure, according to TMZ.com.

His representative is urging fans not to worry, insisting, "He's OK."

Randy was last seen in public at Conrad Murray's medical license review hearing on Monday. The doctor stands accused of administering the anesthetic Propofol which killed Randy's brother Michael.

Jackson recently spearheaded a campaign to open Glendale, California's Forest Lawn Cemetery to fans of the King of Pop, so they could pay their respects to his brother on the first anniversary of his death.
