Television talk show personality Larry King will host a two-hour, "two-screen" telethon to raise awareness of what people can do to help victims of the massive oil spill in the Gulf of Mexico.

The special, airing on CNN's Larry King LiveMonday night, will feature guest stars such as teen pop singer Justin Bieber, movie stars Cameron Diaz and Robert Redford, comedian Kathy Griffin and a special performance by rocker Sting, CNN said in a statement.


The telethon is expected to raise funds for United Way, The National Wildlife Federation and The Nature Conservancy, all of which are non-profit organizations helping people and wildlife hurt by the oil spill along the U.S. Gulf Coast region.

Guests on the TV show will talk with King and sit at telephone banks taking viewer calls and donations.

The "second screen" aspect of King's telethon involves the use of computers, where people can participate via social networks such as Facebook or Twitter by signing into a special "Social Suite" hosted byAmerican Idol star Ryan Seacrest.
