David Duchovny has sought solace in a famous book as he struggles with sex addiction - and it's not the bible but none other than Russell Brand's memoirs.

The X Files star is said to be engrossed in the comedian's autobiography, My Booky Wook, and apparently views its tales of sexual highs and lows as a way through his own struggles.

A source says, "David has been greedily devouring Russell's pieces on the topic in his autobiography 'My Booky Wook', his interviews, podcasts and stand-up routines.

“Women throw themselves at your feet when you become a celebrity. David and Russell became dependent upon it to relax after their busy job."

David recently entered a rehab clinic to fight his addiction, amid speculation that his marriage to Tea Leoni was crumbling because of his infidelity.
