Kim Kardashian hit the red carpet on Friday night outside the Sugar Factory American Brasserie, opening inside the Paris Hotel in Las Vegas, and showed off her date for photographers: her 13-year-old sister, Kylie Jenner, making her debut on the Vegas party scene.

Other guests spotted at the sugar-themed bash included Playmate Holly Madison, former Spice Girl Mel B, 'Lifestyles of the Rich and Famous' legend Robin Leach, actor Esai Morales, MTV starlet Whitney Port, DJ Havana Brown and a brigade of models in colorful corsets festooned with double-D-cupcakes.

Kardashian, who celebrated her 30th birthday in Vegas last year, tweeted her excitement on her way to the event: "Vegas baby! Heading to Sugar Factory! I brought my little sis @KylieJenn here to Vegas w me, she's never been before!"

Little sis Kylie (both TV personalities are daughters of Kris Jenner) weighed in with a "Vegas, Baby!" on her Twitter account, and posted a photo of the pair en route to the party on a private plane.

Lollipops and frothy drinks were served to guests, and Kardashian surely received kudos from partygoers about her first single, 'Jam,' released earlier this week.
