TMZ caught the "Heroes" star arriving at LAX early this morning (she did the Letterman show in NY yesterday), where Panettiere looked absolutely thrilled (insert sarcasm here) when photogs reminded her that she could finally buy cigarettes. More importantly, Hayden also reminded the snappers that she can purchase porn now that she's 18. Bring on the smut!
Of course, not only is she able to buy it ... but she could also legally star in it too.
