Calabasas, California - The Kardashian-Jenner clan was full of tricks and treats over the weekend, and of course, celebrated Halloween in style.

Nobody takes on Halloween quite like the Kar-Jenners.

However, the Keeping Up with the Kardashians stars were short a member this year after Khloé Kardashian revealed on Friday that she and her three-year-old daughter True had both tested positive for Covid.

While the two quarantined, the rest of the reality TV family dominated the spooky holiday with their creative attires.

And in true Kardashian form, one person sparked some romance rumors this weekend.

Here's how the Kar-Jenners celebrated Halloween with their fabulous fashion and fun.

On Friday, Kim Kardashian and Pete Davidson set the internet ablaze.

In photos obtained by People, the two were spotted holding hands while riding a rollercoaster together.

However, fans shouldn't get too carried away, because sources claim that the pair is "just friends."

Plus, Kourtney Kardashian and Travis Barker also joined in the amusement park festivities, pointing to a light-hearted group outing.

Nevertheless, the SKIMS owner continued her Halloween fun.

On Sunday, the 41-year-old shared clips on her Instagram story of her metallic, space cowgirl ensemble at Kourtney's Halloween bash.

The KUWTK alum didn't show off her entire getup, but viewers were able to see her shiny matching cowboy hat and plunging bodysuit.

Yet, Kim should be wary. Now that she was spotted with the Saturday Night Live star, the internet sleuths will be keeping on eye on the two going forward.

In fact, they've already reported that she arrived in NYC on Monday morning – where Pete also returned this weekend!

Will the two have another meet up soon?

Next up, the newly engaged couple continued their Halloween fun by paying homage to one of their favorite classic flicks.

Kourtney and Travis recreated looks from the 1993 film True Romance.

It's not the first time the couple has made reference to the movie on social media. In March, Travis sported a tattoo with a line from the movie, in what many mistook to be Kourtney's handwriting.

The Poosh owner emulated Patricia Arquette's character Alabama by sporting pink leopard-print leggings and a sheer blue top, paired with a blonde wig.

Travis channeled his inner-Christian Slater and wore a Hawaiian shirt with a retro bomber jacket and black shades.

The two couldn't keep their hands off of each other as they did an adorable shoot, showing off their creative costumes – and continuing their heavy PDA.

All in all, these two have got the hots for each other – and it shows.

Kylie Jenner and Travis Scott were all about their family this Halloween.

The expecting mom showed off her growing baby bump with a skin tight all-black suit, a matching leather coat, and cat ears.

The Astroworld rapper chose to go as the iconic bad guy, Michael Meyers.

Their three-year-old daughter Stormi looked adorable in a blue-green mermaid ensemble.

Kylie also shared a pic of herself with her mom Kris Jenner, who also wore similar outfit and cat face paint to her billionaire daughter.

"In full mommy mode this Halloween," the 24-year-old captioned the shot.

The beauty mogul started celebrating Halloween early this year. Earlier this month, she released a new makeup line that paid tribute to A Nightmare on Elm Street, and threw a Halloween dinner bash at her mansion.

Therefore, it's understandable that she chose to stay more low-key this weekend – but there's always next year.

Last, but certainly not least, Kendall Jenner stunned in one of her most creative Halloween ensembles to date.

The supermodel wore a Mars Attack costume and boy, did she deliver.

On Sunday, Kendall posted a series of snaps from the look, where she sported a red and white body-hugging jumpsuit, pointy high-heels, dramatic blue eye shadow, and a perfect red-lip.

But, the pièce de résistance was the model's towering blonde wig that was over a foot tall.

Talk about dedication.

Kendall also shared some clips on her IG story partying the weekend away with Justin Bieber and The Weeknd while enjoying her 818 Tequilla brand, which she released earlier this year.
