Let's take a look at all the developments that have happened so far:
Khloe Kardashian comments on rumors that Tristan cheated on her with Jordyn:
A source told ET that Tristan and Khloe split because of ongoing trust issues. Last April, Tristan made headlines when he was caught cheating on her with multiple women while she was pregnant with their daughter, True, but the two eventually reconciled.
“There were trust issues again and she has been down that road before," the source said of their recent breakup. "She has to be strong for herself and True. Everyone is extremely disappointed.”
"One of my writers was there," Lee claims. "And Tristan you took everybody's phone but you let them stay. Jordyn came in, y'all were smoking hookah, she was all up in your lap, you was all over her, touchy feely, and you let the girl stay the night until seven in the morning. Now, that happened, that's a fact."
"And I don't want want to hear nobody trolling Khloe and talking about, 'It's a Kardashian curse, it's Khloe's fault, this and that,' no," he continued. "If a n**** ain't sh*t, he ain't sh*t ."
He later addressed Kylie.
"The fact that Kylie, your best friend was at the house doing all that, get her out now and get him out too," Lee concluded.
But Malika took it one step further when she later commented on another Instagram post that showed Kylie's daughter, Stormi, smiling, and joked that she was "waiting for Jordyn to pack her sh*t and get out of Kylie's house."
On Wednesday, just one day after the cheating rumors broke, ET learned that Jordyn was moving out of Kylie's home. Kylie shared in a video for Vogue last June that the two were living together.
"Kylie is extremely upset about everything that is going on with Khloe and her best friend, Jordyn," a source told ET. "Jordyn is a sister to Kylie, and she’s extremely shocked this could happen, as is the whole family."
"Kylie is trying to get all the facts before she makes up her mind, but for now Jordyn isn’t staying at Kylie’s," the source continued. "Kylie needs her space and also wants to respect her sister, Khloe. The future of their friendship hangs on the facts."
“The worst pain is gettin' hurt by a person you explained your pain to,” she wrote. The next message read: “Somebody needs to hear this… That betrayal was your blessing!!!!”
Khloe then posted, “If they ask you about me, tell them: ‘She was the only person that loved me with honesty, and I broke her.’”
Earlier, she also liked a tweet that read, “@khloekardashian, don't let anyone ever say this is your fault!. He is a sick man and if it's true, then she is a terrible woman, both terrible people that do not deserve your love. TRUE does and [you're] doing great showing that love."
Other removed photos include the massive heart-shaped rose display Tristan got Khloe for Valentine's Day, a photo of them kissing near the water and a pic that was taken during a recent beach vacation. However, some pics still remain of the NBA star -- mostly from the earlier days in their relationship -- though she's disabled comments on those particular posts.
Despite all the drama, Khloe and Kylie are still tight:
A source told ET on Thursday that despite the shocking cheating allegations between Tristan and Kylie's BFF, the sisters are still as close as ever.
“Khloe and Kylie are extremely close, and this incident only solidified how strong they truly are," the source said. "Khloe and Kylie have been in constant communication. Khloe and Kylie both like to confront an issue head-on, although different this time."
"Kylie was the person who told Khloe about Tristan’s cheating the last time," the source added. "This does put Kylie and Khloe in an awkward spot, but at the end of the day, the family bond will always win.”
