Kelly Osbourne has decided to go green - she's pledged to give up drinking bottled water to help the environment.
Ozzy Osbourne's daughter feels guilty sipping so much spring water because of the landfill mountain created by empty plastic containers.
The rock offspring has decided to have a more environmentally-friendly lifestyle - she's quitting her habit and buying a compost bin to help global warming.
Taking to her page, Osbourne writes, "I have decided to go fully green no more bottled water and im (sic) getting a compost bin tomorrow! It got to a point where every time I reached for a bottle of water from the fridge I felt guilty."
