Halloween parties were supposed to make you scream because of terrifying things, but Kylie Jenner and her BFF Stassie Karanikolaou took this year's Halloween to the next level.

Jenner and Karanikolaou recreated Madonna and Britney Spears' looks during the 2003 MTV Music Awards. Way back in 2003, Spears and Aguilera teamed up as back-up vocals for Madonna's "Hollywood" at the VMA. While the performance was not yet over, Madonna kissed both singers on their lips.

It was a typical costume plans, but not until the two also relived one of the pop culture legends: the sudden kiss between Madonna and Spears.

Jenner completed the full-look costume with a microphone, hat and Madonna's signature blonde hair. As for Karanikolaou, she sported Britney Spears' outfit during 2003 VMAs, as well. The self-made billionaire and her BFF posted a tribute for the pop stars by dancing to "Like a Virgin" on their Instagram account, as well as the quick peck between the two before they burst out laughing.

The family of Jenners and Kardashians have shown countless, unimaginable Halloween costumes. Last year, they went as Victoria's Secret Angels and as usual, gone viral.

The "Twinning" Moments of the BFFs

Earlier this week, the two both had eye surgeries to achieve the "better than 20/20 vision". Karanikolaou recorded the whole surgical procedures on her Youtube Channel, and fans can see that during the post-operation, Jenner could not "rise and shine" yet.

They threw a party after their LASIK surgery to celebrate their "newly-born" eyes. Jenner also said that her sight was just born and that day during the party was its birthday. The two were seen filing their bellies with mango martinis at Nobu.

Jenner and Karanikolaou's friendship started at their mutual friend's home and at the bookstore named "Barnes & Noble".

"It all started when I met this beautiful bomb a** blonde at Barnes and nobles," Jenner said in a 2015 interview for Teen Vogue.

Besides going out to nightclubs in matchy-matchy outfits, they also recently hanged out in Turks and Caicos in line with the celebration of the launch of Kylie Skin.

Like Mother, Like Daughter

Since Jenner only posted one updated regarding her Madonna Halloween costume, her fans speculated that it was not yet her main costume for this year. While waiting for the "chief" look, it turned out that it was not only Jenner who had pulled out a unique Halloween costume for this year.

Her one-year-old daughter, Stormi Webster, seemed to win Halloween's Best Costume for this year as she channeled her mom's looks during the 2019 Met Gala. The lavender gown with removable feather sleeves was coupled with the same colored wig and a jeweled-bag to complete the cute little girl's costume.

Jenner shared several photographs of her child on her Instagram account and said that she could not handle how Stormi was able to look like her.
