Silver screen legend Elizabeth Taylor passed away at the age of 79 today, and stars of all ages have reacted to the sad news of her death.

Close pal Elton John told CNN, "We have just lost a Hollywood giant. More importantly, we have lost an incredible human being." Barbra Streisand added, "It's the end of an era. It wasn't just her beauty or her stardom. It was her humanitarianism. She put a face on HIV/AIDS. She was funny. She was generous. She made her life count."

Former President Bill Clinton and Secretary of State Hillary Rodham Clinton released the following statement:

    "With the passing of Elizabeth Taylor, America has lost one of its greatest talents and fiercest advocates for HIV/AIDS research. Born in England, Elizabeth became thoroughly American royalty. For more than a generation, she brought to life unforgettable characters on film, and her tireless efforts to combat AIDS brought hope to millions of people around the world. We were honored to host her at the White House in 2001 when she received the Presidential Citizens Medal for her relentless crusade for more AIDS research and better care."

Taylor was admitted to Cedars-Sinai Medical Center last month after suffering congestive heart failure symptoms, and she was with her four children at the time of her death.
