Carey to appear on telethon

Singer Mariah Carey is expected to make a public appearance on Friday, when she will join a series of musical guests and actors on America: A Tribute to Heroes, the multi-network broadcast telethon put together by ABC, NBC, CBS and Fox to raise money for victims of last week’s attacks on America.

The 31-year-old singer, who was hospitalized for a mental and physical breakdown in July, and relapsed in September, will sing her 1993 hit “Hero,” a publicist for Virgin Records told Reuters.

Joining the singer will be fellow musicians Bon Jovi, Billy Joel, Tom Petty, Bruce Springsteen, the Dixie Chicks, Neil Young, Faith Hill, Stevie Wonder and Paul Simon.

Among the movie personalities appearing will be Jim Carrey, Will Smith, Cameron Diaz, Robert De Niro, Julia Roberts, Tom Hanks, and Robin Williams.

The telethon, which is being produced by Joel Gallen of MTV Movie Awards fame, will raise money through telephone and online donations for the victims. Music and television artists are donating their time and talents on the show.

According to TV Guide, the event will take place in Los Angeles and New York and air Friday at 9 p.m. live in Eastern and Central time zones and tape-delayed in the Mountain and Pacific time zones.

The Spanish-language channels Univision and Telemundo, PBS, radio stations, and Yahoo! will broadcast the show, Reuters reported.

According to the Hollywood Reporter, Carey‘s Aug. 21 album release, Glitter, has received poor reviews by critics and fans, falling below expectations with a No. 7 debut on 116,325 units scanned, according to SoundScan figures.
