Khloe Kardashian spent Halloween weekend in the presence of her serial cheating ex Tristan Thompson.

The reality TV star, 38, was glimpsed in a TikTok video from a family Halloween party — posted by niece North West, nine — where she was joined by the basketball player, 31, and their daughter True, four, as well as their baby son, whom they welcomed via surrogate in July.

She later took to Instagram to share the very first picture of their newborn baby son who was dressed as the cartoon character Tigger.

Khloe looked to be dressed as a cat for the occasion, sporting face paint, a black bodysuit, and black cat ears, with Tristan behind her holding an Iron man helmet.

Though the rest of Tristan’s outfit didn’t suggest that he dressed up as the Tony Stark character, as he wore a black Nike shirt, black joggers and tennis shoes.

Khloe’s blonde tresses were worn down in a straight style, and the Good American founder appeared to be smiling in the short clip.

Meanwhile True stood next to her mom, and was adorable in an Owlette costume – from the Disney Junior show PJ Masks.

Baby brother: Khloe also shared a heartwarming photo of True in an Owlette costume, holding her baby brother – who was dressed up as Tigger – in her arms

First photo: Khloe shared a glimpse of her baby son wearing sneakers, captioning the snap, ‘Owlette and Tigger aka True and Baby Brother. (Shhhhh…. But I can’t wait for Halloween to be over)’

Khloe also shared a heartwarming photo of True holding her baby brother – in her arms.

The little one was turned away from the camera, and wore a Tigger costume.

‘Owlette and Tigger aka True and Baby Brother. (Shhhhh…. But I can’t wait for Halloween to be over),’ she captioned the photo.

The united public front comes after Khloe’s frustration with lying ex Tristan came blurting out as she screamed in front of a packed premiere screening crowd at the premiere of The Kardashians.

‘Liar’: It comes after Khloe branded the basketball player a ‘liar’ as she watched the premiere of The Kardashians featuring Tristan talking about wanting to expand their family; Pictured 2018

Wow: ‘I was like, “This is just so awkward,” cause it’s like, what a crock of s**t. Like what the f**k? And I believed you and I was listening to you and I was receiving everything you said, but you’re a f***ing LIAR!’ Khloe says in confession

The reality star was joined by her whole family in Hollywood back in April, which was featured on this week’s episode of The Kardashians.

During one scene in the premiere where Thompson says he wants to ‘expand’ their family, Khloe screamed out, ‘LIAR!’ as the crowd applauded.

‘When I was watching the show and Tristan was on and telling… I don’t even know what he said because I blacked it out… but it was like, “We’re so great,” or whatever the f**k he was saying,’ Khloe says.

Welcoming: The second season began with Khloe welcoming her second child with Tristan via surrogate, after the first season ended with the bombshell revelation that Tristan had fathered a child with another woman; Pictured 2022

‘I felt as if the whole theater was staring at me and I was like, ‘This is just so awkward,’ cause it’s like, what a crock of s**t. Like what the f**k? And I believed you and I was listening to you and I was receiving everything you said, but you’re a f***ing LIAR!’ Khloe says in confession.

The second season began with Khloe welcoming her second child with Tristan Thompson via surrogate, though it was revealed in the second episode that the premiere episode was actually filmed in August 2022 while the rest of the season takes place several months earlier.

The first season ended with the bombshell revelation that Tristan had fathered a child with another woman, though the second episode of Season 2 featured another bombshell.

Cute: Another part of the video saw Kim with her other daughter Chicago, four, who donned a black dress

Out of this world: Meanwhile North – whom Kim shares with ex-husband Kanye West, 45 – showed herself dressed up in a frightening alien mask

Their five-year on-off relationship imploded in December 2021 when DailyMail.com exclusively revealed the NBA star had fathered a child with personal trainer Maralee Nichols while he was still involved with Khloe.

By the time Maralee and Tristan’s son Theo was born in December, Khloe and Tristan’s surrogate was already pregnant with their new baby.

North, nine, also included her mom, Kim Kardashian, 42, in the TikTok video which featured Khloe and Tristan.

Another part of the clip saw Kim with her other daughter Chicago, four, who donned a black dress.

Spooky! The decorations at the party featured a spooky mummy

Haunted graveyard: Another decoration featured a daunted graveyard

Meanwhile North – whom Kim shares with ex-husband Kanye West, 45 – showed herself dressed up in a frightening alien mask.

Earlier in the day her sister Kourtney Kardashian and Travis Barker absolutely nailed a Bride of Chucky couples costume that saw the newlyweds transform into the pair of murderous dolls.

Kourtney, 43, and Barker, 46, each donned spot-on looks while attending a party at Khloe house on Sunday.

Khloe featured the couple in her Instagram story, treating her 278 million followers to her insane Halloween decorations.

Despite Halloween being Khloe’s ‘least favorite holiday,’ the Kardashians star clearly went all out when it came to decorating her L.A. mansion.

The mother of two took her fans on a tour of her fabulous home.

Ghoulish white wrappings lavished every inch of her main entrance as mummies guarded every corner, with one even hanging down from the ceiling.

Decorations ranged from classic white skulls and pumpkins to an enormous pink rabbit and the party was certainly a family affair as costumed children appeared throughout Khloe’s story.

But no costume could beat Kourtney and Travis’s serial-killer-possessed pair of married dolls.

The aliens have landed: Even though gravestones and aliens filled Khloe’s backyard, nothing could frighten the Kardashian kids

The couple strolled around Khloe’s party holding hands, making themselves the highlight of the elaborate afternoon.

Kourtney sported a black leather biker jacket, black ribbon choker and goth makeup. A veil crowned her blonde wig while a simple wedding dress formed the bulk of her matrimonial look.

The Blink-182 drummer rocked a pair of creepy overalls with a multi-colored sweater emblazoned with childish stripes.

A red mane of frizzy hair flamed out from behind Travis’s chilling mask as he carried a large kitchen knife in the hand that wasn’t holding onto his wife.

The two have been virtually inseparable after tying the knot in an extravagant Italian wedding in May.
