Three years ago today, actress Brittany Murphy died at the age of 32.

Known for her breakout role in the 1995 hit "Clueless," Murphy appeared in such well known films as "Girl, Interrupted," "8 Mile," and "Sin City." Murphy also voiced the character Luanne Platter on the FOX series "King of the Hill" from 1997 to 2009.

Despite attaining a degree of success early on, Murphy's film career began to wane in 2003. Films like "Uptown Girls," "Little Black Book," and "Love and Other Disasters" were a critical and box office disappointment. By 2009, a number of her films went straight to video and the actress had turned to TV movies.

The star was also known for her singing abilities. In 2007, Murphy was featured on Oakenfold's "Faster Kill Pussycat" track. The star also showcased her vocal skills while voicing the character Gloria in "Happy Feet."

Murphy married screenwriter Simon Monjack in 2007. Just over three years later, Murphy reportedly collapsed in the bathroom of her Los Angeles, Calif., home. According to TMZ, she was rushed to Cedars-Sinai Medical Center where she was pronounced dead on arrival.

According to the Huffington Post, Assistant Chief Coroner Ed Winter determined that the cause of her death "appears to be natural." In February 2010, CNN reported that Murphy's death was an accident caused by "a combination of pneumonia, an iron deficiency and 'multiple drug intoxication.'"

As Fox411 reported, Murphy's death was the result, in part, of an overuse of prescription drugs such as Topamax, Ativan, and Propranolol.

The actress was laid to rest at Forest Lawn Hollywood Hills on Christmas eve.

Tragically, Monjack died months later on May 23, 2010 in the same house were Murphy met her demise. According to PEOPLE, the 40-year-old died from similar causes to his wife, including pneumonia and sever anemia. The site also reported that some prescription drugs were found in his system.

In January 2011, the Hollywood Reporter published "The Final Difficult Days of Brittany Murphy," by Alex Ben Block. The shocking article revealed that Murphy was frustrated with the state of her career, struggling with body image issues, and felt the pressure to take care of her husband and mother, Sharon Murphy, who remained close (uncomfortably so, to some) to her daughter's late husband after her death.
