Khloe Kardashian is reeling after multiple reports on Tuesday that her boyfriend, Tristan Thompson, cheated on her with several women, a source close to the Kardashians tells ET.
The source says Khloe's mom, Kris Jenner, has flown to Cleveland, Ohio, to support her 33-year-old pregnant daughter, and that the rest of the Kardashian family has also been in communication with Khloe and are working on seeing her as soon as possible.
“Khloe is completely devastated," the source says. "Tristan is a man Khloe built a life with and saw as her forever. Khloe’s mother, Kris, flew to Cleveland to be with her and support her in whatever she needs."
As for Khloe and Tristan, the source says their future is up in the air.
"The most important thing is Khloe having a healthy pregnancy,” the source notes.
A source also tells ET that Khloe's sister Kim is flying from Los Angeles to Cleveland on either Thursday or Friday to be by Khloe's side.
“Khloe has the full love and support from her sisters during this difficult time,” the source says.
Meanwhile, Keeping Up With the Kardashians is currently in production, with the Kardashian family in the middle of filming while Khloe prepares to give birth to her and Tristan's first child together, ET has learned. Multiple sources close to the E! production tell ET that the show's producers will determine how the scandal plays out on TV in the coming days, and whether it becomes a storyline on future episodes of the show.
Photos and videos were published by multiple outlets on Tuesday that allegedly show Tristan being intimate with unknown women. A source who knows Tristan tells ET that the scandal looks bad for the 27-year-old NBA star.
“This whole thing is a mess," the source says. "But anyone who believes Tristan is an innocent guy who doesn’t cheat isn’t being honest with themselves.”
Khloe and Tristan have yet to comment on the reports. However, that hasn't stopped others from weighing in. On Tuesday, the 27-year-old NBA star's ex, Jordan Craig, appeared to comment on the reports. Tristan shares a 1-year-old son, Prince, with Jordan.
"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," she wrote on Instagram Stories. "Wishing peace for everyone."
Amber Rose -- who's feuded with Khloe in the past -- also reached out to Khloe on Tuesday.
"I know we've had our differences in the past but my heart is broken for you sis," Amber wrote on Instagram Stories. "Smh no one deserves to feel that pain especially during such a sensitive time."
