It was a weekend with the Kardashians when Kourtney and Khloe, as well as step-brother Brody Jenner, were all in Las Vegas to host at clubs.

Reality star Kourtney Kardashian hosted a season preview at Marquee Dayclub at the Cosmopolitan of Las Vegas on Saturday afternoon with a group of friends.

Wearing a Roberto Cavalli animal print dress, she told reporters on the red carpet that her boyfriend Scott Disick is doing well in rehab. She says the entire family tries to get together to watch "Keeping Up With The Kardashians" each week.

While at Marquee Dayclub, Kourtney Kardashian set off the first fireworks of the dayclub season.

On Friday night, the youngest Kardashian, Khloe, hosted at 1 OAK Nightclub at the Mirage with friends such as Malika Haqq, model Dorion Standberry, actress Lauren London and recording artist and actress Cassie Ventura in tow.

After dining at Stack Restaurant & Bar at the Mirage, she was greeted by fans ogling her white Balmain dress that showed off her curvy figure.

The group drank Grey Goose, Don Julio 1942 and Champagne. Kourtney even asked someone in the crowd to buy her Champagne and shots.

Over at Tao Nightclub at the Venetian, step-brother Brody Jenner returned for his “One Night Stand” deejay residency with William Lifestyle.

Olympic gold medalist Shaun White also happened to be there, helping his sister Kari celebrate her 30th birthday, as was former San Francisco 49er wide receiver Jerry Rice, who popped into the DJ booth as Jenner bowed and told the crowd to give it up for the NFL legend.
