Jaymes Vaughan of the Chippendales tweeted this cellphone pic today while the guys were in the middle of their annual Chippendales calendar shoot.  The Chippendales calendar was one of the very first “hunky guy” calendars that took off in the early 80s, and to this day one of the biggest selling calendars on the market.

Those are some SERIOUS abs, kids.  Don’t try this at home – these guys are professionals.
