Randy JacksonRandy Jackson, one of Michael's younger brothers, was taken to the hospital, The Associated Press reports.

An anonymous source close to the family, who was not authorized to speak to the media, told the AP that Jackson experienced mild chest pains and was taken to Huntington Memorial Hospital in Pasadena for testing.

Randy is currently waiting for his results, but the source concludes that he had a mild heart attack, although there has been no official confirmation of that diagnosis.

Jackson was recently in court with the rest of his family at a hearing for Dr. Conrad Murray -- who stands accused of involvement in Michael's death.

There, a judge ruled that Murray could still practice medicine in the state of California.
