Kylie Jenneris still reeling after finding out that her longtime best friendJordyn Woodshooked up withKhloé Kardashian‘s then-boyfriendTristan Thompson, a source tells PEOPLE.

“Kylie had a rough week,” the insider says. “She is still devastated about Jordyn and had an argument with Travis after she checked his phone and saw something that she didn’t like.”

Days after news first broke about the Thompson-Woods cheating scandal,TMZreported that Jenner, 21, had accused her boyfriendTravis Scottof cheating, which prompted him to cancel his Feb. 28 Buffalo, New York, show and remain in Los Angeles. (Scott announced on Twitter that he had both canceled and rescheduled his concert due to illness.)

However, a rep for Scott, 26,strongly deniedto PEOPLE that he was unfaithful or that he and Jenner had fought about cheating. A rep for Jenner had no comment.

According to the source, “Travis says he didn’t cheat. Kylie was upset at first but seems better. She isn’t breaking up with him.”

Woods, 21, appeared onJada Pinkett Smith‘s Facebook Watch talk showRed Table Talkon Friday to share her side of the cheating scandal, claiming that Thompson, 27, kissed her while she was on her way out of an afterparty at the NBA player’s house two weeks ago.

“On the way out, he did kiss me,” she told Pinkett Smith, who asked if it was a peck or something more romantic. “No passion, no nothing, on the way out. He just kissed me. Like a kiss on the lips, no tongue kiss, no making out, nothing.”

Although Woods has admitted she made a mistake, she’s denied being the reason why Thompson and Kardashian, 34, are no longer together.

“I’m no home wrecker,” Woods said. “I would never try to hurt someone’s home, especially someone that I love. And someone that I’ve seen — has a beautiful daughter. I never was trying to steal someone’s man.”

Still, she said she was “not here to play the victim.”

“I didn’t tell the truth to the people that I loved,” she said. “Not because of malicious intent, but because I was just scared.”

Minutes later she added, “Tristan is equally to blamebut Tristan is the father of my child. Regardless of what he does to me I won’t do that to my daughter. He has been addressing this situation PRIVATELY. If Tristan were to lie publicly about what conspired,then yes I would address him publicly as well.”

However, in a series of emotional tweets on Saturday, Kardashian revealed that she’dhad a change of heart, as she placed the blame fully on Thompson.

“This has been an awful week & I know everyone is sick of hearing about it all (as am I). I’m a rollercoaster of emotions & have said things I shouldn’t have,” shewrote. “Honestly, Tristan cheating on me & humiliating me, wasn’t such a shock as the first time.”

The mother of one went on to share that she wants tofocus on her “blessings,”which include her 10-month-old daughterTrue, whom she shares with Thompson.

“She has basically lost part of her world,” said the source. “She is very, very upset. She always trusted Jordyn with everything.”

The two have been best friends since high school, with Woods moving in with Jenner in recent years (she has sincemoved out), accompanying her on lavish vacations and helping take care of Jenner’s daughter. Woods and Jenner evengot “married”with a commitment ceremony on a trip to Peru together that was chronicled in the season finale ofLife of Kyliein September 2017.

“Kylie just can’t make sense of what happened,” the source said. “She still has so many questions for Jordyn.”
