VENTURA, Calif. >> James Horner’s agent says the Oscar-winning "Titanic" composer was the pilot who died in a Southern California plane crash.

Michael Gorfaine says Horner was flying the single-engine aircraft that crashed and burned Monday morning in a remote forest area 100 miles northwest of Los Angeles.

Although it is expected to take several days for the Ventura County coroner to confirm Horner’s death, Hollywood is mourning him.

James Cameron, Ron Howard, Celine Dion and many other celebrities are remembering the 61-year-old as a talented man and a good friend.

Horner won two Oscars for "Titanic," including one for the song "My Heart Will Go On," which became a big hit for Dion.

He also received Oscar nominations for the scores to "Alien," ”Apollo 13," ”Field of Dreams," ”Braveheart," ”A Beautiful Mind," ”House of Sand and Fog" and "Avatar."
