Hugh Hefner's son Marston celebrated this week's big announcement -- that his dad bought back control of the Playboy empire -- by partying at STK in Vegas.
But more importantly, he looks JUST LIKE HIS DAD!!!
Our pals at SpyOnVegas.com snapped this shot of Marston out last night with a girl that would make his daddy proud.
And speaking of daddy, Hugh's power move will make it easier for him to pass over control of the company to his sons -- 21-year-old Marston and younger brother Cooper.
