Today (Monday) we celebrate rockstar Joan Jett’s 56th birthday! As her time in The Runaways and her solo career show, she’s always been into leather, heavy eye makeup and, despite a few departures, the same haircut for decades.

Not only does she actually pull off this mullet-like, piece-y style, she’s worn it from short to long, slicked-down to teased. And although this cut might not work for just anyone, Jett flaunts it along with her overall bad ass vibe.

Here are some photos from then and now that show why we’ll always love Joan Jett… and rock ‘n roll.
