Kylie Jenner might be just 13 years old, but that didn't stop big sister Kim Kardashian from bringing her to a posh restaurant opening in Sin City Friday night.

"Vegas baby! Heading to Sugar Factory! I brought my little sis @KylieJenn here to Vegas w me," the reality queen, 30, tweeted. "She’s never been before!"

An excited Kylie tweeted back, "Vegas baby!" and posted a pic of her and Kim in a private plane en route to the event.

At the party, the sisters chatted with former Spice Girl Mel B. and sucked on complimentary lollipops.

No doubt, the DJ probably played Kim's debut single, "Jam."

Kylie tweeted about the tune, "I can't get JAM, my sister Kimmies new song out of my head!"
