Kourtney's younger sister Kim was photographed over the Labor Day weekend showing off her new hue, with honey tones, but Kourtney was showing that its a fairly normal occurence for the Kardashian women.

 Last weekend Kourtney let her own hair down while partying in Las Vegas with her "squad". The Keeping Up With The Kardashians star was out in Vegas as part of a promotional part for Kardashian Khaos, and tweeted several fun photos for her 9.4 million Twitter followers to see.

One picture showed the group kicking back in their bath robes and sipping on champagne, while another saw the ladies all dressed in black ahead of their night out, with the caption: "Squad ready. #viva #las #vegas."

The group then headed out to the club by limo and continued snapping away. "70s limo ride," she tweeted, followed by "Vegas get ready" and "Up in tha club!"
