Kelly Osbourne Shows off Sexy Slim Figure for Pussy Cat Dolls
Kelly Osbourne has been looking hot lately. First she lost all that weight on Dancing With the Stars, but now she’s not only kept it off, but gotten tinier!

We first took notice at last weekend’s Emmys in her form-fitting black Tony Ward gown looking skinnier than ever. She was all smiles showing off her smaller waistline.

Then we got a load of the pics Kelly uploaded to her Twitter last night for her Pussy Cat Dolls appearance. Kelly performed with the PCD at the Viper Room doing “13 Men” and “Big Spender.”

"It's the first time I've really danced since filming 'Dancing with the Stars,' but it's so different,' she told her fans. "This isn't stiff ballroom - it's slinky and sexy!"

Kim Kardashian, Eva Longoria and mom Sharon Osbourne reportedly attended the soiree. Kim took to Twitter to support Osbourne, writing, "[Kelly] just killed it!!! She sang and danced and looks amazing!!!!! Love these costumes!"

Kelly also tweeted to singer Mya saying, “@MISSMYA it was amazing getting to work with you again you sounded so good tonight xoxoxox you better stalk me!!!”

She tweeted to creator Robin Antin, “@robinantinpcd i cant thank you enough for tonight i had so much fun! i fucking love you robin!!!!!!!!”

She looks incredible! Thanks to ET, we have Kelly's performance below!
