TwitPic Theater went underground for a few weeks, but this week, we’re back and doing it in style with the a special birthday edition. Hugh Hefner and his son Marston celebrated their shared April 9th birthdays at the Playboy Club on Saturday night. Joining the birthday boys were friends, family and of course dozens of Playmates who documented the festivities via social media. Check out some highlights below.
