GGO Birthday - JOAN JETT

The hard-rockin, hard-livin' Joan Jett, ex-Runaway, turns an unbelievable 52 today. Is it just me that finds it hard to wrap their mind around the idea of women rockers are growing old? I've grown accustomed to seeing men rock stars grow old such as Mick Jagger and Robert Plant. JOAN JETT… FIFTY TWO!? Weird. She's still looking hot though.
