Blake Lively -- Gets Thigh-High in NYC

Blake Lively is bootylicious.

Wearing an old school Jennifer Lopez diva hat, a '70s black mini-dress and a ridiculously hot pair of open-toed thigh-high boots, the happily married 25-year-old former "Gossip Girl" star strutted her gorgeous blonde and leggy stuff on the streets of New York City on Tuesday.

Apparently the high fashion walk off was all part of some magazine photo shoot, but who really cares about that ... the important thing is that she looks AMAZING!

Damn you, Ryan Reynolds! Damn you.
