Madonna has been slammed for investing in environmental damaging companies. The singer - who headlined Live Earth London on Saturday night, which was held to raise awareness of global warming - is said to have invested approximately £2.1 million ($4.2 million) into companies named among the world's biggest polluters.

Madonna's Ray of Light Foundation allegedly owns shares in companies including Alcoa, Ingersoll Rand, BP and several others associated with oil exploration and refining.

Orlando Bloom is building an eco-friendly house in the British countryside. The "Pirates Of The Caribbean" star decided to construct his own green home because he can't afford to buy a property in London.

The actor complained to Britain's Daily Express newspaper: "I was trying to buy somewhere in London but couldn't afford it. It is not the actors making money, it is the boys in the City."
