Troubled rocker Pete Doherty, who is going through some major drug problems, is set to premiere his new tell-all autobiographical film at an Austrian porn theatre.

The 29-year-old rocker, lead singer of the band Babyshambles, will reveal details about his old love supermodel Kate Moss and his other equally troubled friend Amy Winehouse in the movie, due to be screened Thursday in Graz.

"Some of it is very revealing," said a friend.
