Madonna and Demi Moore are throwing an Oscars party.

The "Hung Up" singer will again team up with her actress friend and her manager Guy Oseary for a glitzy bash on February 22 following the success of the bash they threw last year at Guy's Los Angeles home.

Drew Barrymore's friendship with Cameron Diaz helped her overcome her troubled childhood. The 33-year-old actress insists her "Charlie's Angel's" co-star helps keep her sane and is one of her closest confidantes.

She said: "Cameron's one of the greatest friends anyone could ever have. She has so much love and positive energy to her. I've always felt like she's my big sister. "

Cameron Diaz has ruled out starring in "Shrek the Musical." The actress - who voices Princess Fiona in the animated film franchise - attended the Broadway opening of the musical on Sunday but has no plans to tread the boards herself.

When asked if she would like to play Fiona on stage, Cameron replied: "No. Absolutely not. What they do up there is, to me, impossible. It's wonderful, though. They've done such a great job. They worked really hard, and it really pays off."
