It was announced yesterday that Whitney Houston's will excludes ex-husband Bobby Brown and leaves everything to her only child, Bobbi Kristina. The 19-year old will receive portions of her trust when she turns 21, 25, and 30. Houston's untimely death recalls that of many well known icons. In terms of wills, several celebrities took precautions to set up an updated trust in the event of their death. Other's endured unexpected occurrences prior to their deaths that did not permit such careful planning. Below are 5 examples of celebrity wills. 

John F. Kennedy, Jr: One of the most tragic deaths of a public figure, John F. Kennedy, Jr and his wife Caroline Bessette-Kennedy died in a plane crash while flying to his sister's (Caroline Kennedy Schlossberg) wedding. His death fueled talk of a Kennedy Curse. Since his wife also perished in the crash and he had no children, Kennedy's will left $100 million to his sister's children. 

John Lennon: In 1980, John Lennon was shot by a disturbed fan at the entrance of the Dakota in NY, where he lived. Mark David Chapman shot the famed musician 7 times and the star was pronounced dead on route to the hospital. In his will, Lennon left most of his estate to his wife, Yoko Ono.  

Marilyn Monroe:  In 1962, at the age of 36, Marilyn Monroe was found naked in her bedroom with no signs of life. Many believe that the famed sex symbol committed suicide, while others claimed she was murdered. The circumstances surrounding her death remain one of Hollywood's greatest mysteries. Her will left most of her possessions and money to family and friends. 

Elvis Presley: In 1977, Elvis Presley died after overdosing on at least 10 different prescription drugs. Presley's well-thought-out will has allowed him to become the second wealthiest dead celebrity, aside from Michael Jackson. The beloved entertainer left much of his fortune to his family. His father, Vernon Presley, grandmother, Minnie Mae Presley, and his only child, Lisa Marie Presley were the major inheritors. His daughter is now the only living relative mentioned in his will. 

Anna Nicole Smith: When Anna Nicole Smith gave birth to a daughter in 2006, her son Daniel came to the hospital to visit and died. The bizarre tragedy was the result of Daniel's addiction to prescription drugs. Just months later, Smith died from an overdose of such drugs as Valium and Ativan. In the short span of time between her son's death and her own, Smith did not change her will which left the bulk of her estate to him.
