Hugh Hefner turned 85 on Saturday and his VERY handsome son Marston is the big 21 Sunday, so the two men high-tailed it to Vegas for a Playboy-style birthday party. RadarOnline.com has all the pictures.
Partygoers flooded into the Palms Casino Resort for the bash that began at the Playboy Club and continued into Moon nightclub.
Hugh's bride-to-be Crystal Harris was there, of course. So were another 30 past Playboy Playmates going back to Deanna Brooks, Miss May, 1998.
Hugh and Crystal spent the weekend in the aptly-named Hefner Sky Villa atop the Palms Fantasy Tower.
"I'm a very lucky cat and I know it," Hugh told RadarOnline.com in an exclusive interview.
He and Crystal are set to wed on June 18.
