Maternity leave is officially over! Kourtney Kardashian gets back to work as she jets into Las Vegas to host club summer season opener

She gave birth to baby Reign four months ago and now it's time to get back to the business of being a Kardashian.

On Saturday Kourtney Kardashian jetted into Las Vegas by private jet to host the season opener of the Marquee Dayclub at The Cosmopolitan.

The mother of three left Los Angeles with seven girlfriends in tow declaring: 'And, we're off...girls trip! Vegas!'

Kourtney, 35, chose a dramatic leopard print patterned, floor length, wrap dress for her red carpet appearance.

The chiffon robe covered a halter neck black bikini that peeped from underneath.

She teamed the dress with tan leather wedge sandals barely visible beneath the hem of the billowing outfit.

Take a walk on the wild side in Kourtney's Roberto Cavalli dress

When it comes to animal print, there's one designer that rules the roost and that's Roberto Cavalli. It's the ultimate in signature styles, so there's no surprises at all to learn that Kourtney's maxi dress is by the brand.

Upon spotting the reality star rocking this fab frock, we experienced a case of dress déjà vu. Our instincts were right, as Khloe Kardashian wore it back in 2011!

We're very jealous of those Kardashian sisters - sharing clothes means they've basically got the equivalent of five wardrobes each! Plus, there's no need to go vintage shopping. Instead they can just raid each other's closets to unearth a retro gem like this Cavalli number!

As it's from a previous season you can no longer buy the exact dress, but if you click right you can shop a really similar style at Shopbop. If you're not wild about the price points though, channeling Cavalli is easy to do on a budget as the high-street is chock-a-block with lovely leopard print designs - River Island's maxi is definitely going to be a summer hit!

For a change it was Kourtney that was preparing to let her hair down, not her wayward partner Scott Disick.

The troubled father of three is currently in rehab in Costa Rica where he is being treated for his intensive partying with a controversial psychedelic treatment.

But according to TMZ, Scott is on the verge of quitting the 21 day regime and returning to Los Angeles after just one week.

The showbiz website said he had a flight booked home for Monday saying he was too busy to commit to the full program.

Also at the Vegas event was Australian performer Sia with a typical attention-grabbing look.

The Grammy-nominated 39-year-old completely covered her face with a blonde wig as is the norm for the Chandelier singer.

She teamed the hair piece with an off-white trouser suit and a red wide-brimmed sun hat and towering red sandals.
