Tristan Thompson may be a professional basketball player, but his recent moves off the court have caused quite the stir.

In case you’ve been living under a Kardashian-free rock, Thompson, Khloé Kardashian’s boyfriend—and father of her newborn daughter True—has apparently been cheating on her. Now, big sis Kim Kardashian West is opening up about the sad situation.

In an Ellen Degeneres Show preview clip that was posted on Friday, Kim told Ellen that the cheating scandal is “so messed up.” “Like, I don’t even know how to describe it other than it’s just so f-cked up,” the reality star said.

Kim went on to say: “We really were rooting for Khloé. And we still are. She’s so strong and she’s doing the best she can. It’s a really sad situation all over. I kind of made this rule with my brother: if there’s a baby involved…I’m going to keep it cute and keep it classy and not talk too bad…I’m going to try not to say anything too negative because one day, True is going to see this.”

Kim’s appearance on Ellen—which airs in full on Monday—is the first time a close member of the fam has spoken out about the scandal. Just a week before Kim’s statement, People reported that Khloé is living in Thompson’s Cleveland pad with True, but the athlete is not crashing with them.

According to the outlet, even though Thompson is not living with his new family, he comes by to visit True. A source even told the outlet that the reality star “has very little to do with” Thompson and that she can’t wait until she is cleared to fly again so she can move back home to Los Angeles.

The family drama all started after TMZ posted a video on April 10 of 27-year-old Thompson making out with a woman and “motorboating” another at a Washington, D.C. hookah lounge back in October, causing the Kardashian crew to swiftly unfollow the b-ball player on Instagram, according to Elle.

But the TMZ makeout vid isn’t the only proof that Thompson hasn’t been faithful to the 33-year-old Good American designer. On April 9, the Cleveland Cavaliers player was spotted heading into a hotel in New York with a woman (reported to be a bartender named Lani Blair) around 5 a.m. According to TMZ, the woman was apparently seen, “hanging all over Tristan at an NYC nightclub earlier in the evening.” Thompson was in town for a basketball game, while a very pregnant Kardashian was apparently back at his place in Ohio.

Then, actor Gabrielle Union somehow got caught up in the cheating scandal. The 45-year-old Being Mary Jane star found herself in the middle of the mess when The Shade Room posted footage of the woman Thompson allegedly cheated with at the hotel, and pointed out that Union was in the background of the pic. Pretty soon after the post went up on April 12, Union responded to the outlet to clear her name.

The We’re Going to Need More Wine author responded to The Shade Room‘s post directly by commenting on its IG account. She wrote: “Don’t know her. Didn’t see her. I was enjoying my night with my mama and aunt. We ain’t involved in this.” Can’t a girl go out with her family without getting entangled in a cheating drama anymore?!

Apart from all the social media shiz—and Kim’s comments on Ellen—the Kardashian sisters themselves have been pretty silent about the cheating sitch. Kim and Kourtney even continued posting pics of themselves lounging in bikinis on vacation when the scandal broke, causing people to speculate that the fam was trying to downplay the drama. As for Khloé? On April 9, shortly before her baby arrived, she posted a pic of her kissing Thompson on IG with the caption: “We are ready whenever you are little mama.”

While the Kardashians have been relatively quiet, after the news broke, Khloé’s BFF Khadijah Haqq McCray posted a pointed John Wooden quote on Instagram that reads: “the best thing a father can do for his children is to love their mother.” *OH SNAP*

And McCray isn’t the only one throwing shade at Thompson. When the NBA player hit the court for the first time after TMZ released the video, the crowd audibly booed him. Some fans in the crowd even held up signs stating their support for Kardashian.

Kardashian announced she was expecting in December on Instagram, more than a year after she and Thompson first started dating in September 2016. Whatever’s going on between the two, we are sending positive vibes to the new mama and her baby girl.
