From the most exclusive red carpet events around the world to the city streets, Hollywood’s hottest stars were dressed to rock and shock on Wednesday – and RadarOnline.com has all the photos in our daily fashion feature.

The stars of Breaking Dawn were out promoting Part 1 of the highly anticipated film and all three leading ladies looked sexy to the max! While Kristen Stewart dazzled in a goth glam Roberto Cavalli gown, Nikki Reed in Michael Kors, and Ashley Greene in a custom designed Donna Karan gown, both showed some skin with their cutout style creations at the New York screening.

Oh, Lady Gaga! The sassy singer paraded around without her bra on, wearing a color-blocked Roksanda Ilincic dress with Christian Louboutin heels and a Philip Treacy sperm-style fascinator.

Other style scores included Zoe Saldana and Minka Kelly, who both rocked to-die-for curve-hugging Michael Kors dresses to the Michael Kors Boutique opening on Robertson Blvd, while a la mode misses were courtesy of Shenae Grimes, who wore those acid wash denim shorts AGAIN, and Snooki, who matched her booties to her hair.
