Scan from the Daily News via Bebe Buell's memories 'Rebel Heart'. The caption says: 'A MODEL'S HELP MET'S LIV A COVER: Even supermodels - New York's top growth industry - are taking second jobs these days. Paulina Porizkova is promoting Liv Tyler, 15, the daughter of aerosmith's Steven Tyler and former model Bebe Buell. Paulina snapped shots of Liv (including this one with her mom) and shopped them around town. It paid off. Liv's got the cover pf next month's 'Seventeen'. Liv also read for the new Arnold Schwarzenegger flick.
