Our favorite “Hangover” star got down and dirty on the beach in a hot pink ladies swimsuit for his latest photo shoot with “Vanity Fair”. The star posed for several seductive shots which appear in this months edition of the magazine.

The HBO's Bored to Death star revealed in his interview with the magazine that Robert Downey Jr whom Zach stars opposite in “Due Date” told him that he needed acting classes.

“[Robert] told me in front of 45 extras that I needed acting classes. I like to call him ‘another Irish mistake.'" The film hits the big screen on November 5th.

Judging from these photos Im not sure if Zach has a future in swimsuit modeling!
