The reality star looked somber in the late night clips shared on her Instagram
Just hours after PEOPLE reported that Kylie Jenner‘s longtime BFF Jordyn Woods was moving out of Jenner’s house amid allegations she cheated with Khloé Kardashian’s boyfriend Tristan Thompson, the Kylie Cosmetics mogul popped up on social media in some sexy selfies.
Jenner, 21, who has laid low on Instagram since the cheating scandal news broke, posted two late-night selfie videos from her kitchen in which she flaunted her stomach in a leopard print cropped pajama top and matching bottoms. In the first Instagram Story clip, the star zoomed in to draw attention to her abs while covering her face with her cell phone. But in the second, Jenner leaned her head on her hand while giving a somber look to the camera.
“goodnight,” she simply captioned the first video with a crescent moon emoji.
Multiple sources confirmed to PEOPLE exclusively that Jenner’s best friend Woods, 21, is now “moving back to her mom’s house” after she allegedly made out with Thompson at a house party. “It’s been a difficult time and [Woods is] broken up about it. She’s heading home to be with her mom,” an insider revealed.
The entire Kardashian family had trouble coming to terms with the allegations when news first broke, according to a source.
“When they first started hearing on Monday that Tristan made out with Jordyn, no one really believed it,” the source said. “That Tristan would be inappropriate, yes everyone knows that he can’t behave, but that Jordyn would make out with him, it first seemed like a made up rumor.”
“It wasn’t anything they wanted to drop,” the source added. “So several family members reached out to people they believed had been at the party. And they were told it was true.”
The allegations have been hitting Jenner especially hard.
“Jordyn has been like Kylie’s sister. They were inseparable, and always together,” a source said. “Jordyn often helped Kylie with Stormi. Kylie was always so excited to have Jordyn around. It seems Kylie isn’t sure what to do, but it seems impossible for her to keep Jordyn around.”
The source continued, “Life won’t be easy for Jordyn if the girls close their doors. And this doesn’t seem like the kind of betrayal that can be forgiven.”
While Woods has remained silent since the news broke, Kardashian, 34, has not. The mom to 10-month-old True (who she shares with Thompson) liked a fan’s tweet reading, “Dont let anyone ever say this is your fault!. He is a sick man and if its true, then she is a terrible woman, both terrible people that do not deserve your love. TRUE does and ur doing great showing her that love.”
She also posted a series of emotional quotes on Instagram Story Thursday morning after making her first public appearance since the scandal with best friend Malika Haqq at the opening of PrettyLittleThing’s new store on Wednesday night.
“The worst pain is getting hurt by a person you explained your pain to,” the first quote read.
Another slide read, “Somebody needs to hear this…That betrayal was your blessing.”
A final quote posted to Kardashian’s Instagram Story said, “If they ask you about me, tell them, ‘She was the only person that loved me with honesty, and I broke her.’”
Thompson has denied all the allegations, writing “FAKE NEWS” in a since-deleted tweet.
Reps for Kardashian and Thompson did not return PEOPLE’s requests for comment. Woods’ rep had no comment.
