Kendall Jenner and Kylie Jenner’s attempt to keep their night out on the town a secret this week was all in vain. The underage, teenage reality stars were caught leaving a 21-and-over club, the Vignette Lounge in West Hollywood, Calif., Tuesday.

According to a report from TMZ, the “Keeping Up With the Kardashians” starlets, 17-year-old Kendall and 16-year-old Kylie, were spotted attempting to discreetly exit the club late Tuesday night. A video of the event shows the sisters leaving with the help of security guards who covered them in blankets to hide them from paparazzi. Despite their attempts to remain anonymous, photographers captured of an image of the pair looking the worse for wear. “At the end of the night, Kylie and Kendall looked ... tired,“ TMZ said regarding the suspicious images.

The nightclub was reportedly celebrating its weekly Wax Rabbit event at the time, in which the topless dancers perform to hip hop music to create a "voyeuristic" experience. “Let your jaw drop at our scantily clad dancers throughout the club, and even more revealing topless dancers upstairs,” says the lounge on their official website, adding, “in addition to bottled favorites. Remember to order a stripper pole for the amusement of your lady friends! We promise a truly unforgettable night.”

According to TMZ, the reality stars broke the law by attending the alcohol-serving joint, a venue on Melrose Avenue that only allows musicians 18 and over to enter as an exception to the rule. An unidentified official of the Department of Alcoholic Beverage Control is reportedly looking into the matter. There is no confirmation that an investigation will occur as a result of the Jenners' attendance at the hot spot.

The allegations of underage partying follow a report in August that claimed the teens were using their family’s Malibu beach home as a party house. According to a report from Star magazine via CelebDirtyLaundry, the reality sisters allegedly spent the summer “partying hard” at the residence without adult supervision. “The neighbors are in an uproar because there is ’round the clock partying on Kris’ property,” said the report, which also claimed teens were spotted “passed out” with empty “beer bottles and half-smoked blunts” nearby.
