SJP is a butterface to most men. Yeah, they would 'hit it'---but only from the back. Britney has just gone down the tubes mentally, which is enough to keep men at bay. And, Madonna? She's older and played out to MAXIM readers.
MAXIM is shallow as hell, anyway. They vote Serena Williams as "sexy" because of her body and ass when a lot of men say they would only do her if a paper bag was within reach.
