AceShowbiz - Kylie Jenner accidentally crossed paths with Tristan Thompson at a party. A few hours after calling him the "worst person on the planet" in the newly-aired "The Kardashians" episode, the Kylie Cosmetics founder reportedly had a "nice exchange" with the NBA player.

On Thursday night, June 9, the youngest daughter of Kris Jenner and the basketball player "did run into each other" at social media star Stassie Karanikolaou's birthday bash in Hollywood. A source spilled to Page Six that they had a "nice exchange" as they said "hi" to each other. The insider further noted that there was "no tension or uncomfortable energy at all," despite his tumultuous past with Khloe Kardashian.

For the bash, Kylie donned a silver corset top which she paired with dark blue jeans and black sunglasses. In the meantime, Tristan opted for a black Supreme shirt and camouflage jacket. He also added some thick chain necklaces.

Several other Hollywood A-Listers, including Kendall Jenner, her boyfriend Devin Booker, G-Eazy and Addison Rae, also partied late into the night for the influencer's birthday. Tyga, who dated Kylie for three years before her relationship with Travis Scott (II) began, showed up at the party as well. However, they "didn't run into each other or hang out at all."

Kylie's not-so-awkward exchange with Tristan happened just hours after "The Kardashians" episode in which the famous family discovered the 31-year-old athlete had cheated on Khloe again aired.

In the episode, Kim Kardashian broke the news about Tristan's baby drama to mom Kris and sisters Kylie as well as Kourtney Kardashian. While she was on the phone with Kris, Kim said, "His whole declaration is in this thing, which says, 'I, Tristan Thompson, met this girl in Houston. I slept with her on my 30th birthday.' " Kim further noted that Khloe wasn't aware of the legal filing, adding, "So I sent it to him and I said, 'Does Khloe know about this?' Khloe doesn't even know."

Before the momager could respond, Kim hung up the phone to call Kylie. The 24-year-old refused to believe at first, responding to the news shared by her sister, "You're lying." An enraged Kim replied, "No, I'm not f**king lying. I'm shaking for her. My soul dies for her." The Kylie Skin founder then asked, "Is Tristan the worst person on the planet?"

Kim then read the paperwork on her phone, before exclaiming in anger, "He's saying that he slept with her!" Further breaking down the timeline of Tristan's affair with Maralee Nichols, Pete Davidson's girlfriend said, "He's asking for a paternity test and admitting that he had sex with her. Khloe threw him his 30th birthday. So he went home from the 30th birthday party, went to Houston to play on the road-we can check his schedule-and then slept with this girl."

Kim saw the baby drama as "the biggest sign" for Khloe to stay away from Tristan. "The whole thing that's so sad is she wants a baby boy. And now this girl's having a f**king baby boy, a f**king random that he sleeps with one night. F**k him," Kim lamented with Kourtney responding that Khloe didn't "deserve this." Kylie then stressed that it had to be Khloe's "final sign."

Tristan confirmed he's the father of Maralee's baby in January after news broke about her giving birth to his baby boy in December 2021. Shortly after, the Canadian basketballer apologized to Khloe in an Instagram Story that read, "Khloe, you don't deserve this. You don't deserve the heartache and humiliation I have caused you."
