Cameron Diaz hosts this week's "Saturday Night Live" with Grammy winning, ground-breaking punk band Green Day on April 9.

Making her third hosting appearance, Diaz appears as her new environmentally conscious MTV travel show "Trippin'" debuts. The versatile actress made her debut opposite Jim Carrey in the smash hit "The Mask." She followed that with several smaller, independent films including "The Last Supper" and then returned to blockbuster territory with "My Best Friend's Wedding" opposite Julia Roberts.

Her performance in the title role in the comedy hit "There's Something About Mary" scored critical accolades as well as huge laughs. Her varied credits that followed include: "Very Bad Things," "Being John Malkovich," and "Any Given Sunday" and "The Sweetest Thing."

She starred opposite Drew Barrymore and Lucy Liu in the popular "Charlie's Angels" films. More recently, Diaz made two dramatic and award-nominated turns in "Vanilla Sky" opposite Tom Cruise and with Leonardo DiCaprio and Daniel Day Lewis in Martin Scorsese's Oscar nominated "Gangs of New York." Most recently, she provided the voice for Princess Fiona in the animated blockbusters "Shrek" and "Shrek 2" with Mike Myers and Eddie Murphy.

Diaz is joined by musical guest Green Day who make their SNL debut. The punk trio will perform from their triple-platinum, Grammy winning rock opera "American Idiot."

The band is enjoying its best reviews in their 12 year career for the ambitious record which All-Music Guide called "a masterpiece" and prompted Entertainment Weekly to proclaim "Green Day Saves Rock" on one of the band's many magazine cover appearances.

"American Idiot" is currently residing in Billboard's Top 10 Album charts and the record's third single "Holiday" is already climbing. In addition, the band just announced its first stadium tour.
