PHOTOS: Dancing Divas In The Best & Worst

From the red carpet to the streets, stars were dressed to rock and shock the day on Monday in the best, worst & wackiest fashions‹and RadarOnline.com has all the photos in our daily feature.

Dancing with the Stars announced their latest batch of celebrity contestants on Monday, celebrating with a soiree at STK in Hollywood.  Former Girl Next Door Kendra Wilkinson showed up to the bash, looking sexier than ever in a super tight and short black mini dress, which showed off her boobilicious bod to perfection.

Kirstie Alley also looked gorgeous, wearing a one-shouldered purple patterned summer dress‹without shoes!  The Cheers alum, who most recently starred in her own reality show Kirstie Alley’s Big Life, should probably think about investing in some fancy footwear to go with her gorgeous dresses!

Alec Baldwin was celebrated at the Museum of The Moving Image in NYC by a bunch of lovely ladies. While Kristen Wiig looked tres chic in a black dress, Tiny Fey rocked a sophisticated suit, and Mariska Hargitay looked fab in an eccentric floorlength.

Richard Simmons wore a burgundy velvet warm up suit (which should have been retired in 1979) for a day of traveling, while Helena Bonham Carter recycled her favorite floral frock leaving Los Angeles.

Reese Witherspoon spent the day after Oscar with her fiancée Jim Toth and her adorable children, wearing a super cute striped top, while Kate Beckinsale headed to the set of Underworld 4, dressed to thrill in a white coat and skinny jeans.
