Bring out the balloons, candles, and birthday cake, because it's time to wish the Auntie Kenny a happy birthday!

Kendall Jenner turned 24 on November 3; however, before her exact birthday, the supermodel pulled out a star-studded Halloween-slash-birthday party over the weekend.

Kendall celebrated her birthday in advance at the Blind Dragon nightclub in West Hollywood. Her party was star-studded and filled with her closest friends and family, who were all wearing their most sophisticated Halloween costumes.

Celebrating her birthday together with celebrating the Halloween season was an epic idea, so kudos for you, Kenny!

Kendall has always been wishing to dress up as a "witch" every year for Halloween, but the "Keeping Up With The Kardashians" star went with a different get-up for this year's spooky season.

Kendall brought her party on Instagram via Instagram Story, as she posted clips and photos of herself wearing a fairy-inspired costume. It went together with a metallic gold feathered mini-dress, an oversized pair of champagne wings, and a gorgeous headpiece.

The star then finished her fairy look with synthetic elf-like ears that added more likeness to her fairy costume look.

Kendall is very family-oriented and just like her sisters, family always comes first. That's why the Kardashian-Jenner clan was present at her celebration party, even Kourtney Kardashian, who threw a Halloween party at her home with her kids earlier in the same day.

At Kendall's party that evening, the 40-year old hot mom was dressed up as a country superstar, wearing a hot pink button-up tucked into chrome high-waisted shorts. Kourtney then topped the look with a crystal cowgirl hat and white cowgirl boots.

She posted photos of herself in the outfit and captioned: "howdy y'all"

Kendall's younger sister and self-made billionaire Kylie Jenner would not miss her party for the world -- what kind of a sister would, right? Kylie was spotted wearing a butterfly fairy costume, which happened to be her sixth Halloween costume for this year.

The star went for a blonde wig that added just the right amount of touch to her fairy-like look. Just like her sister, Kylie had elf-like ear prosthetics to make her look like a real fairy.

She brought her look on social media and even went for a butterfly Instagram filter on her face in a short clip of herself in the fairy costume.
