From the red carpet to the streets, stars were dressed to rock and shock this Monday in the best and worst fashions and RadarOnline.com has all the photos!
Mila Kunis had an incredibly red hot day in NYC. The bigscreen bombshell hit The Today Show early in the day, raising the temperature in a v-neck Versace cocktail dress, which she paired with nude Jimmy Choo heels. That evening, she changed into something a little sexier, hitting the premiere of Friends with Benefits in a skintight Lanvin number!
Emma Stone was also dressed to thrill on the red carpet, wearing a look from the Giambattista Valli Fall 2011 collection, which consisted of a tight red sweater and a pink peplum skirt, paired with nude Christian Louboutin heels.
Though Lady Gaga upped the wacky factor wearing a plastic skirt and lace face mask in NYC, she got some crazy competition from fellow singer Porcelain Black, who hit the Late Show with David Letterman in an equally shocking look.
Rihanna managed to make a men's night shirt look sexy on the streets of NYC, while Adrienne Bailon made a splash at the Kooey Swimwear Australia Fashion Show during Mercedes-Benz Fashion Week Swim, wearing a gorgeous pale grey and blue dress with Yves Saint Laurent sandals.
