From the star-studded events of the Royal weekend in Los Angeles to the streets of Beverly Hills, Hollywood’s hottest stars were dressed to rock and shock – and Breaking Celebrity News has all the photos.

The biggest social event of the weekend was with without a doubt, the BAFTA Brits To Watch Event in Los Angeles, where bigscreen bombshells mingled with the future King and Queen of England. While the Duchess of Cambridge dazzled in Alexander McQueen, and Gossip Girl Blake Lively looked angelic in Marchesa, Jennifer Lopez sported totally inappropriate attire. The sassy singer showed way too much skin in an incredibly sexy Emilio Pucci gown, which would have scored her best dressed status at the Grammy Awards, but didn’t quite mesh at the conservative soiree.

As for wacky, Lady Gaga achieved the title dressed in arrest-worthy attire – as a cop!

Zoe Saldana looked sensationally summery at The Foundation Polo Challenge in Santa Barbara, wearing a gorgeous gown from the Chloe Resort 2012 collection with Valentino wedges and a Lanvin clutch for her afternoon with the Royals, while Shenae Grimes was a 9021NO on the streets of Beverly Hills, experiencing a cutoff catastrophe.
