Tonight's "Hope for Haiti Now" earthquake relief telethon promises to be so star-studded it calls to mind the supergroup charity performance for Africa in 1985 known as "We are the World."

It also will be nearly impossible to miss. The two-hour event will be the most televised benefit in history, airing simultaneously on 25 networks, according to CNN.

Hosted by the Oscar-winning actor George Clooney in Los Angeles and musician Wyclef Jean in New York, the 8 p.m. ET event is being presented by MTV.

Among the stars set to perform are Justin Timberlake, Taylor Swift, Madonna, Bruce Springsteen, Beyoncé, Stevie Wonder, Jennifer Hudson, Mary J. Blige, Shakira, Alicia Keys, Dave Matthews, Jay-Z, Rihanna and Coldplay.

Making appearances will be Ben Stiller, Meryl Streep, Muhammad Ali, Will Smith, Brad Pitt, Robert Pattinson, and former president Bill Clinton.

Proceeds will go to the Red Cross, Partners in Health, Yele Haiti Foundation, Oxfam America, UNICEF, United Nations World Food Programme and the Clinton Bush Haiti Foundation.

Airing the telethon live will be CNN, FOX, NBC, ABC, CBS, BET, The CW, HBO, MTV, VH1, CMT and the Discovery's eco-lifestyle television network, Planet Green.
