With news that Tristan Thomspon cheated on a heavily pregnant Khloé Kardashian, it appears the soon-to-be mom is watching her worst nightmare become a reality. As Koko’s due date gets closer and closer — with fans predicting she’s due to give birth to literally any day now — those closest to the Keeping Up With the Kardashians star say her greatest fear was that Tristan, who seemingly dumped his first baby mama to get with Khloé, hasn’t changed his ways. Check out the video above to see what she had to say about his previous transgressions.

In light of her fears about her baby daddy — which began long before the most recent video of him entering a hotel with two unidentified women surfaced — Kris Jenner was encouraging her daughter to make a plan to give birth in SoCal like all of her sisters, but the always-headstrong Khloé refused. “[Khloé’s] been totally stressed out,” a source tells In Touch. “She and Kris clashed over where she should give birth.” Khloé and Tristan have long been planning to welcome their first child together in Cleveland, where he plays for the Cavaliers, while Kris tried to encourage her daughter to stay in LA and film the birth for their reality show.

Even though she couldn’t see eye-to-eye with her mother on where to give birth to her daughter, Khloé knew that her life in Cleveland was far from perfect. “She loves Cleveland, but she goes through bouts of loneliness, especially when Tristan isn’t around,” the source says. “She’s kept herself busy by shopping for baby clothes online and decorating the nursery.”

While, sadly, it seems like Khloé’s suspicions about her beau — nicknamed “Third Trimester Tristan” — turned out to be right, it doesn’t seem likely she’ll be able to forgive him this time. “Tristan’s f–ked up bit time. He knows it, and Khloé is pissed,” another source told Life & Style. “Khloé’s done. She’s so f–king done. Her stomach hurts so bad and it’s not from the pregnancy — she could kill Tristan right now.”
