Hugh Hefner’s live-in girlfriends, reality stars of The Girls Next Door, Kendra Wilkinson, Holly Madison, Bridget Marquardt are posing for Guitar World magazine’s 2009 buying guide The girls all pose together for one cover shot and each one of them apparently has her own separate cover photo. So that makes 4 covers! We all know Hefner’s favorite girlfriend is Holly, who’s yours?

more photos after the jump…

Do the girls play guitar? I have no idea but my guess is: NO! I would guess that most of the Guitar World magazine’s readers are guys so hot chicks = good promo! Don’t forget to get your copy  of Guitar World Magazine’s 2009 Buying Guide coming out on June 19th.
