From the red carpet to the streets, stars stepped out on Monday dressed to rock and shock and RadarOnline.com has all the photos in our daily fashion feature.
Justin Bieber's gal pal Selena Gomez sizzled on The Late Show with David Letterman, wearing a to-die-for Emilio Pucci mini. The lace sleeved and leather accented mini dress clung to her curves in the most divine way possible, while her zipper adorned heels scored her a flawless finish.
Steven Tyler hit the American Idol PaleyFest dressed to shock (not rock) in tacky and wacky threads. Wearing leopard bell bottom jeans with a nude leather jacket, brown boots and a long scarf, the Aerosmith frontman looked just a tad worse than fellow judge Randy Jackson, who paired a psychedelic neon scarf with a black leather biker jacket, jeans and metallic cowboy boots.
At the 2011 School of American Ballet Winter Ball in NYC Michelle Trachtenberg looked marvelous in a lilac embroidered Marchesa gown, which she paired with a clutch from the same collection and David Yurman earrings, while Kelly Rutherford looked Gossip Girl glam in a sleek one-shoulder gown, which featured embellished detailing.
Kristen Wiig ravished at the Los Angeles premiere of Paul, wearing a flirty Stella McCartney Wrap dress with Roseark jewels and Rene Caovilla heels.
Other a la mode misses included Kate Moss, who dressed up for St. Patty's Day early in a neon green gown, Olivia Munn, who stepped out in figure-unflattering duds and Janice Dickinson, who sported a putrid purple and puke green look.
