What is the difference between oh-so-sexy and too-sexy? Just ask Kyra Sedgwick and Venus Williams, who score our Best and Worst looks of the day respectively. While The Closer star had us panting for air during an appearance on The Late Show with David Letterman, the tennis pro had a little too much to share, while dining out in Los Angeles.

Kyra hit the streets of NYC in figure flattering frock from Antonio Berardi’s Fall 2010 collection. The green-infused brocade number was perfectly sculpted for the blonde beauty’s petite bod, and featured black side panels, which had a slendering effect. Paired with Casadei black satin platforms and single bangle bracelet, we couldn’t get enough of Kevin Bacon’s beloved!

Though Venus Williams is absolutely stunning and has a bodacious bod, we were a little shocked that she stepped out for dinner on Monday in a white nightie. The grandslam goddess experienced a babydoll disaster, in a barely-there frock, which refused to cover her assets. At least she was wearing flesh-toned pasties!

Snooki was dressed to fly---to Alaska! The Jersey girl was spotted wearing furry boots as she departed her flight from LAX to JFK in true winter fashion, while Emily Blunt deplaned in Los Angeles with her new hubby John Krasinski, looking delightful summery in casual duds. Kelly Bensimon looked ab fab in NYC, showing off her Housewife bod in a crop top and Roxy Olin looked sexy in The City, pairing a pink-piped romper with gladiator sandals and a colorful manicure/pedicure.
