PHOTOS: The Best, Worst & Wackiest Fashions Of The Weekend

From the red carpets of the swankest events to the streets of the world, stars stepped out dressed to rock and shock -- and RadarOnline.com has all the photos in our weekend roundup.

Halle Berry has one of the hottest bodies in Hollywood and isn’t afraid to show it off in sexy style!  The bigscreen bombshell hit Muhammad Ali’s Celebrity Fight Night in Phoenix, dressing her curves in a royal blue Rachel Roy pencil dress, which she paired with t-strap heeled sandals, scoring herself the best look of the weekend.

Leona Lewis has been all about designing her own duds in recent months, hitting the 25th Anniversary Genesis Awards in Los Angeles in the worst yet.

The Brit crooner horsed around in an eccentric equestrian themed number, which even featured a hairy mane!  Other guests at the charitable event included Kristin Davis, who looked pretty in a hot pink Oscar de la Renta and Stephanie Pratt, who looked fem and fab in a Marc Bouwer strapless.

And Padma Lakshmi upped the wacky factor at the 3rd Annual Blossom Ball in New York, barely covering her body in a colorful sari.

Khloe showed off her Kardashian curves at her little bro’s 24th Sin City birthday, leaving little to the imagination in an Alexander McQueen number, while Sonja Morgan looked red hot at the GLAAD Media Awards, wearing a one-shoulder Lorena Sarbu couture gown with a gold hammered belt.

Katy Perry took a little time out of her busy European tour to have a little fun in fabulous fashion. The sassy songbird celebrated her assistant’s 30th birthday in London wearing a Jenny Packham embellished gown with Sergio Rossi heels and tons of Chanel bangles and cuffs, finishing the look off with a Chanel bag. One of Katy’s pals tells RadarOnline.com that the beautiful brunette can’t get enough of Chanel!
