Grammy performers to include Beyonce, Swift

Beyonce and Taylor Swift will perform at the Grammy Awards next month.

The Recording Academy said Tuesday that other performers will include the Black Eyed Peas, Lady Antebellum and Maxwell . Beyonce has 10 Grammy nominations; Swift has eight.

A stage-crashing Kanye West interrupted Swift's acceptance speech at this year's MTV Video Music Awards to say Beyonce should have won for best female video instead. West later apologized.

The Grammys will be presented at the Staples Center in Los Angeles on Jan. 31. The show will air on CBS.

The Recording Academy says additional performers will be announced at a later date.

A cool celebration for Cook in K.C.

Talk about a sweet surprise.

David Cook was home in Kansas City, Mo., to sing the National Anthem at the Kansas City Chiefs game on Dec. 20 — his 27th birthday.

But he didn't just celebrate with a football game. Family and friends surprised the rocker in his suite at the stadium, singing "Happy Birthday" and delivering a Cold Stone Creamery ice cream cake in his favorite flavor — chocolate chip cookie dough.

"My 27th birthday was a great excuse to get a bunch of friends and family together," the "American Idol" winner tells People magazine.

Coroner looks into Murphy leak

Los Angeles coroner's officials are looking into how details of an investigator's report on Brittany Murphy's death were leaked to TMZ.

Assistant Chief Coroner Ed Winter says he doesn't know how the Web site obtained the confidential report. TMZ's report stated the investigator, identified only by last name, noted numerous bottles of prescription medications were found in Murphy's name at the Hollywood Hills home where she collapsed Sunday.

The 32-year-old died after suffering cardiac arrest Sunday. Winter says coroner's officials are looking into whether the "Girl, Interrupted" actress' death was due to natural causes but also want to see the results of toxicology and tissue testing.

TMZ declined to comment on how it obtained the report.
