Yeah, she's a star collectorShe only aims to pleaseYoung celebrities
and the second verse of "Sweet Little Sixteen":
Sweet little sixteen, she just got to haveAbout a half a million famed autographsHer wallet filled with pictures; she gets 'em one by oneBecome so excited; watch her; look at her run, boy
