Kylie and Kendall Jenner allegedly used fake IDs to get inside the Vignette Lounge in West Hollywood, a club in California for 21-year-olds and above. However, the underage girls' camp is denying the accusation that they broke the law.

The Jenner girls, aged 16 and 17 years old, are the daughters of Kris and Bruce Jenner, as well as Kim and Khloe Kardashian's half-sisters.

Both underage girls reportedly entered the sex-themed 21-and-Over nightclub on Oct. 15, 2013. The club, which features Wax Rabbit every Tuesday night, calls it "a new, voyeuristic, hip hop and nudity nightclub experience."

According to TMZ, the club's manager insisted that their bouncers checked IDs at the door and didn't allow anyone inside without it. Apparently, the girls were able to go inside the club because they presented IDs as proof that they are already 21 years of age.

The club manager also said that they did not recognize the Jenner girls because they don't know them and their relation to the famous Kardashian family.

Because underage celebrities usually try to go inside clubs for adults and drink alcohol there, the club manager claims that they are very particular about checking the IDs of those who come in.

However, there is supposedly a loophole to get into the club if one is below 21 years old. That is if the person is a professional musician, and is at least 18 years old. But, Kylie is only 16, while Kendall is 17 and even if they were 18-year old musicians, they still wouldn't be allowed during a night that features topless dancers.

Sources close to the Jenner family claim that the 2 girls did not use fake IDs to get in the said club. The doorman apparently recognized Kylie and Kendall and let them in without asking for proof of age. Plus, the girls were not aware that the club was only for patrons aged 21 years old and above.

But, the Vignette Lounge's manager adamantly insists that they did present fake identification at the door!

Guess it's the club manager's word against the girls.

Their half-sister Khloe Kardashian was seen with Scott Disick as they escorted the Jenner girls inside the club. Surely, they both know that the girls are too young for that kind of scene!

Plus, a photo of the girls looking drunk in their car was also seen as they left the club before 2 a.m.

A Department of Alcoholic Beverage Control official also told TMZ that it looks like both the club and the girls have broken the law. The official says that his department may launch an investigation into this matter.
