Jack Nicholson Seen in Rare Photo Celebrating 89th Birthday

Jack Nicholson made a rare cameo appearance -- and he did so on a very special occasion.

That's right ... the legendary actor turned 89 Wednesday -- and his daughter, Lorraine, celebrated Jack's big day by posting a pic of her daddio on her Instagram Story.

In the photo, Jack's cracking his famous Cheshire grin while clapping his hands with none other than Joni Mitchell sitting on a couch nearby. Lorraine also posted a vintage photo of Jack kicking back while smoking a stogie.

As you probably know, Jack's been keeping a low profile in his old age, trading in his storied Hollywood career for a quiet life behind the scenes. But, as you can see, Jack is still everyone's leading man.
