Lady GaGa has joined the Backstreet Boys and Korn's Jonathan Davis in a boycott of BP oil.

Davis, who is initiating the artists' boycott has encouraged his fellow musicians to abandon the use and purchase of BP fuel, as well as that of any of its affiliates, during their summer tours, he told The AP. The boycott is in response to the oil company's handling of the tens of millions of gallons of oil that are streaming into the gulf and devastating the ecology and economy of the region.

Additionally, Justin Bieber, Cameron Diaz, Lenny Kravitz and Ryan Seacrest are volunteerig their time to appear on CNN's two-hour telethon "Disaster in the Gulf: How You Can Help" this Monday.
