Happy birthday, Hugh Hefner!
The Playboy founder turned 88 years old on April 9 and he's looking better than ever, thanks, in part, to his 27-year-old wife, Crystal Harris.
The cute couple share their adventures on their respective Instagram pages, where Crystal shows off her hubby's funny side (and naked body paint selfies, natch) and Hef posts pics of the couple dressed up for their weekly movie nights ("Casablanca" and "Bad Words" are their recent favs).
Aside from his birthday, Hef had a lot to celebrate this year: Playboy celebrated its 60th anniversary and put Kate Moss on its special commemorative issue.
So, to celebrate Hef's birthday, we take a look at his best Instagram photos, which prove that he's truly young at heart.
