From the red carpet of the swankiest soirees to the city streets, Hollywood’s biggest stars were dressed (and undressed!) to rock and shock on Monday – and RadarOnline.com has all the photos in our daily fashion feature.

Emma Stone knows how to class up a red carpet in sexy style!  The bigscreen bombshell was dressed to thrill at the Worldwide Orphans Foundation’s Seventh Annual Benefit Gala, wearing a Calvin Klein ensemble with black heels and a Jimmy Choo clutch.

Those LMFAO boys sure know how to shock on the stage! Redfoo and SkyBlu hit Much Music’s New.Music.Live in their oh-so-eccentric underwear.  Enough said!

At the 2011 CFDA/Vogue Fashion Fund Awards Zoe Kravitz looked awesome in Alexander Wang, while Olivia Wilde showed some skin in a sexy Cushnie et Ochs cutout dress.
