The couple has been plagued by cheating allegations as Khloe nears her due date, with multiple reports emerging on Tuesday claiming that Tristan has been unfaithful to his pregnant girlfriend.
While a source first told ET that Tristan was doing "nothing more" than speaking with a woman at a New York City club on Saturday night, reports have continued to come forward claiming other instances of his alleged infidelity -- leaving Khloe "devastated," another source told ET.
Here's everything we know about the scandal.
Cheating Allegations First Surface
The first report of Tristan's alleged infidelity was published on Tuesday, after The Daily Mailobtained photos and video of the NBA player at Manhattan bar PH-D on Saturday night. The video appears to show an unknown woman draping her arm around Tristan, before leaning into his hoodie. That's when a source told the outlet the two were "obviously making out."
Was Tristan Thompson Really Spotted Kissing Another Woman?
A source told ET, meanwhile, that "the video going around shows Tristan in a loud club briefly talking to a girl, nothing more. Tristan was there for roughly an hour and left with his teammates. Khloe and Tristan are happy and focusing on the birth of their daughter.”
Not long after, however, The Shade Room published photos of what looks to be Tristan and the same woman heading into a hotel, while TMZ also published a video of what appears to be the Cleveland Cavaliers player kissing and getting cozy with two women at a hookah lounge outside Washington, D.C., in October 2017. Khloe would have been three months pregnant at the time.
Stars Speak Out
Tristan's ex-girlfriend, Instagram model Jordan Craig, quickly took to her Instagram Story to seemingly comment on the drama, writing, "If you respect yourself and you respect others, you would never make light of the misfortune of anyone, nor would you feel indemnified when it comes at the expense of others. Wishing peace for everyone."
Tristan and Craig welcomed their first child together, a son named Prince, in December 2016, about four months after Tristan started dating Khloe.
"I know we've had our differences in the past but my heart is broken for you sis," Rose wrote. "Smh no one deserves to feel that pain especially during such a sensitive time. God bless you and your baby."
Kardashian Family Rallies Together
Both Tristan and the Kardashian family have stayed radio silent about the scandal, but a source told ET that by Tuesday night, momager Kris Jenner had "rallied" the family around Khloe.
"Kris has gathered the family and made sure they would all be there for her," the source said. "They are so excited for Khloe. Her sisters are being super supportive of her… her family is rallying around her."
According to the source, the family "wants nothing more than to believe that [Tristan] is a stand-up guy," but in the meantime, they're focusing on what really matters: Khloe's baby girl.
"The video hasn't stopped the Kardashians from making sure her day will be one of love and respect," the source shared. "They won't let any news change the importance of how beautiful this birth is for Khloe."
"They want her to focus on having a healthy experience," the source continued, adding that Khloe's family was trying to keep her from looking at "any of the news right now."
By Wednesday morning, another source told ET that Kris had flown to Cleveland to be by Khloe's side, while Kim Kardashian West will fly in on either Thursday or Friday.
How Khloe Is Coping
Khloe has been "devastated" by the whole ordeal, a source told ET, but is in communication with her family and leaning on them for support.
"Khloe is completely devastated," the source shared on Wednesday. "Tristan is a man Khloe built a life with and saw as her forever."
As for the future of Khloe and Tristan's relationship, that's still up in the air as she prioritizes her pregnancy and delivering a healthy baby girl in Cleveland.
"The most important thing is Khloe having a healthy pregnancy,” the source noted.
Friends React to the Scandal
A source told ET on Wednesday that Khloe and her family weren't the only ones surprised by the headlines -- her friends were too.
“Friends are shocked and didn’t see this coming," the source said. "They seemed to be in a really good place."
A source close to Tristan, however, disagreed. "This whole thing is a mess. But anyone who believes Tristan is an innocent guy who doesn’t cheat isn’t being honest with themselves," the source said.
Khloe's ex-husband, Lamar Odom, meanwhile, is feeling for his ex-wife, another source revealed, sharing, "Lamar has been telling close friends that he genuinely feels bad for Khloe."
The Show Must Go On?
Through the highs and the lows, the Kardashians keep rolling. Sources close to Keeping Up With the Kardashians production told ET on Wednesday that the show is currently filming, and that Khloe and Tristan's drama might play out on future episodes of the show.
According to ET's sources, the show's producers will determine in the coming days how the scandal plays out on TV.
