Hugh Hefner celebrated his big day by hosting a "Casablanca" movie night at the Playboy Mansion, which has been his birthday tradition for more than 20 years.
The famous ladies man took to Twitter to share a series of snapshots from his soiree, writing, "Tonight we start my weekend birthday celebration with the screening of my all time favorite film Casablanca with family and friends."
He also shared a photo with his wife Crystal Harris, writing, "Here's looking at you, kid." W/ @crystalhefner #CasablancaNight."
All 15 male guests looked dapper in white formal jackets, while 28 female attendees posed for pictures in the foyer.
In honor of this milestone, Hefner also wrote a note to his younger self for the CBS series "Note to Self."
"Asking the world to change is hard, but don't worry, you'll be up to the fight and you will prevail," he wrote to himself. "Those who don't know you will label you a womanizer, but I know the truth -- you're a hopeless romantic."
Gotta love Hef!
