Famous Stars And Straps Celebrates Their 10th Anniversary & 10th Album

Johnson & Johnson heiress Casey Johnson died Monday morning in Los Angeles at the age of 30. No cause of death was given as of press time.

The socialite, who was reportedly engaged to reality star Tila Tequila, was the great-granddaughter of the founder of the pharmaceutical giant and the daughter of Woody Johnson, owner of the New York Jets.

Casey, whose pals include Paris Hilton and Lindsay Lohan, was recently arrested in California on grand theft charges after reportedly burglarizing the home of supermodel Jasmine Lennard, a former girlfriend she used to hook up with.

UPDATE: A law enforcement source told TMZ.com it appears Casey had been dead for several days before her body was discovered.
