Sadie Sink debuts mullet in Stranger Things. 

The Mullet Club now includes Sadie Sink, a Stranger Things actress.

The rising star's most recent hair transformation was revealed by hairstylist Tommy Buckett last week on Instagram.  

Sink, a redhead, posed for the picture while donning a stylish black leather jacket.

As you can see, it's a noticeable change from her customary long appearance. 

She previously starred in the moving big-screen film The Whale with eventual Oscar winner Brendan Fraser.

Though her character Max Mayfield is currently unconscious, Sink is ready for action,

when the fifth and final season of the '80s science fiction drama Stranger Things premieres.

She said on The Tonight Show Starring Jimmy Fallon, "I'd like to see her awake. "I would like for that chapter to be closed,"
