Johnson & Johnson heiress Casey Johnson was pronounced dead Monday morning at the age of 30. Early reports suggest that Johnson, who was said to be engaged to reality star Tila Tequila, died of natural causes.

LAPD spokesperson Sara Faden tells Usmagazine.com, "At this point ... there was no evidence of foul play. The coroner's office will now take over the investigation and conduct their toxicology screenings."
