Perfume Peddling Kim Kardashian's Sin City Sexiness

Closing out the weekend in Sin City, Kim Kardashian was busy tending to her never-ending promotional obligations at the Mirage Hotel & Casino in Las Vegas on Sunday (June 3).

The E! reality hottie showed off her killer curves in a sexy LBD as she did her best to peddle perfume at the Kardashian Khaos store.

Keeping her fans in the know about her Vegas doings, Kim posted a tweet after wrapping things up at the Mirage, as she wrote, "Just finished my perfume launch for True Reflection at Kardashian Khaos, now heading over to Rehab at the Hard Rock! Love Vegas!!!"

Meanwhile, fans of Miss Kardashian are in for quite the night ahead - as the 31-year-old is set to be featured alongside Drake in a special "Punk'd" clip airing just ahead of the 2012 MTV Movie Awards.

Tweeting about the "Punk'd" appearance this morning, the brunette beauty excitedly wrote, "Right before Drop Dead Diva on Lifetime I get Punk'd on MTV at 8pm!!! What a night!"

Along with the MTV Movie Awards spot, Kim can also be seen in her guest role on Lifetime's "Drop Dead Diva" when the fourth season premieres at 9/8c.
