‘90210’ Newcomer Justin Deeley In His Underwear [PHOTOS]

The 4th season of 90210 premieres tonight and they’ve got a new sheriff in town; southern hunk Justin Deeley has saddled up to steam up the sexiest zip code on television.

Justin has landed the recurring role of Austin, a sexy cowboy type who’ll be a potential love interest for AnnaLynne McCord’s Naomi.

Although the show’s trailer pokes fun of his post-pool “package”, these photos of him in men’s board shorts from International Jock indicate that he is one virile young buck. Considering he looks just as great in Calvin Klein Underwear as he does in men’s sleepwear, it’s clear that this new Beverly Hills cowboy is the kind who can ride all night.
