Happy Friday! Seth Rogen Shows EVERYTHING In X-Rated Selfie

Seth Rogen is taking the selfie trend to a disturbing extreme.

The former Freaks and Geeks star proved he's still for some freak in him with a tweet late Thursday in which he's naked and bent over, exposing his rear end and scrotum for all who dare to visit his Twitter page.

The 31-year-old, who took on the Kim Kardashian part in a Bound 2 parody last year, hits the silver screen next month in the comedy Neighbors, co-starring Zac Efron.
