Teens Kendall and Kylie Jenner accused of using fake ID to party at 21-and-over sex-themed nightclub... and authorities may investigate

After taking in the Day By Day fashion show - where Scott Disick was flipped off by model Caroline D'Amore - in LA on Tuesday, the Jenner sisters Kendall, 17, and Kylie, 16, headed out to party with half-sister Khloe Kardashian.
That's what teenagers do, after all.
But the venue they reportedly chose to stop by was a 21-and-over West Hollywood nightclub where minors are not allowed. According to TMZ, the bouncers of the club insist they looked at the reality stars' IDs and they checked out. An investigation may be launched, according to the site. A Kardashian family rep did not return calls to MailOnline.

Clubbing with adults: On Tuesday teenagers Kylie (left) and Kendall (right) Jenner stopped by the 21-and-over Vignette nightclub in West Hollywood

They can't hide: The girls, spotted in the back seat of a Bentley, visited the club's Wax Kitten night which promised nudity and hip hop

Covering up outside the club: Kendall had a black jacket over her head and Kylie put her hand in front of her face after they exited Vignette

Uh-oh: Kendall, 17, seems stunned that she has been caught leaving the club where no one under 18, not even performers, are allowed

Duck! The girls are arm in arm as they try to hide their faces while walking out the doors of Vignette and into their waiting car

The teen sisters were spotted exiting the nightclub, Vignette Lounge (which used to be Leonardo DiCaprio's favorite hot spot Villa).
Kendall even put her black jacket over her head as Kylie ducked while they walked toward their waiting Bentley. As they left Vignette together they were in the same clothes they had worn to the fashion show at LA Live.
They look a bit bewildered as they were photographed heavily.
Khloe was also there, she came with friend Malika Haqq in her white Mercedes-Benz G wagon. Scott - who was allegedly drinking too many cocktails at the Day By Day show - stepped into the lounge separately.

Vignette Lounge did not return calls to MailOnline.

Family was with them: Khloe Kardashian (left), still wearing her wedding bands, also hit the club, as did Scott Disick (right)

Before it got crazier: The sisters just hours earlier with Scott at the Day By Day fashion show where model Caroline D'Amore flashed the stars the bird

To make matters worse, the girls were at the club on a Tuesday night, when the Wax Rabbit event is held. Wax promises a 'voyeuristic' experience with hip hop and nudity, according to the event's Facebook page.
So not only is alcohol served, but topless dancers wander about the place.
No one under 21 is allowed into the club. The only exception is made to the club's performers, but they cannot be under 18 years of age, according to TMZ.

TMZ contacted an official for the Department of Alcoholic Beverage Control that told the site, 'Both the girls and the club appear to have broken the law and could have been cited had they been caught in the act.'
The official added that they may launch an investigation.
It's not clear if the cameras for Keeping Up With The Kardashians were there. The reality show is currently in production on their ninth season.
This isn't the family's first trouble with the law this year. In August Khloe's estranged husband Lamar Odom was reportedly arrested for a DUI in LA and refused a chemical test.

Still bonded: Kendall with father Bruce Jenner just before her parents' split was announced

This scandal comes on the heels of last week's announcement that Kendall and Kylie's parents Bruce and Kris Jenner were splitting after 22 years of marriage. They said they are not looking into divorcing just yet.
In June Bruce moved out of the Hidden Hills family home into a rental in Malibu. The change was explained on their show as temporary and just a need for the Olympian to have his own space.
People reports on Wednesday however that the athlete was 'tired of Kris' ambition.'
The magazine adds that, 'Everything in Kris' life is about ratings,' and to expect to see the breakup detailed on her reality show to help boost ratings.
Both Kylie and Kendall have been spotted with their parents in the past week.
On Oct. 8 they played a round of golf with her father.
On Monday Kylie was spotted holding her mother's hand as they walked through the Topanga Mall, just 10 minutes from their house.
Both Jenner girls have been to several red-carpet events in the past year, most notably the iHeart Radio Festival in Las Vegas in September where both girls partied with Khloe and Kourtney.
Kylie dates Jaden Smith, Will Smith's son, and Kendall has been busy modeling.
Both girls are OPI nail polish spokespeople.
