BRAD PITT and JENNIFER ANISTON are hooked on marijuana, according to American tabloid STAR.

Friends say the Hollywood couple have been trying to keep their drug use a secret for years, but worry they have both started to go too far.

One concerned friend says, "They tell pals their idea of a perfect night is getting high together at home. "They smoke almost every day, and not just in their own house. They're quite open about their marijuana use and are happy to smoke up a storm in public at parties."

Aniston has even boasted to friends that she and Pitt were stoned when they were once introduced to PRESIDENT CLINTON. And Pitt once spent a fortune at his favourite, now closed, drugs paraphernalia shop in Los Angeles, 2000BC.

One former employee claims Pitt is so obsessed with his love of marijuana, he wears a leaf insignia somewhere on his clothing at all times.

Ironically, Aniston is set to play the wife of a man infertile because of his pot smoking in new movie THE GOOD GIRL.
