Never underestimate the power of the perfectly paired pump! Celebrities stepped out last night and as important as the dresses they flaunted were the heels they walked in.

Always donning punchy styles, Riri didn't wear her high-hair, but showed off star-studded ankle boots, shield shades, and rolled up jeans for dinner in NYC. Still fairly new to the city, the usually-stylish Whitney Port had too much going on in her look, teaming heavily-hardwared heels with a purple floral dress for a stroll in Soho.

Uptown, at the 2009 Whitney Contemporaries Art Party in NYC, Herve Leger dresses were the theme of the evening. Melissa George went fashion-forward in a super-mod white, high-collared bandage dress and matching sky-high heels. Lake Bell was horrifically Miss Matched and Ali Larter had smokin' style from the ankle up.

Across the pond in the UK, Isla Fisher turned it out in a "Very Niiiice" mini number!
