"Happy birthday @khloekardashian," the 28-year-old wrote. "You are the most beautiful human I have ever met inside and out. Thank you for being an amazing mommy to our princess True. She is blessed to have someone like you to look up to. I wish you nothing but more success and sending you positive blessing your way. Enjoy your day Koko."
Khloe hasn't publicly responded to Tristan's message, however, she did take to Instagram Stories to write that she is "so overwhelmed by the birthday love" and that "life is beautiful."
Khloe finally ended things with Tristan four months ago, after finding out that he had kissed her friend, Jordyn, at a house party. Last week, we finally saw what happened in the days following the cheating scandal on part-one of the two-part season finale of Keeping Up with the Kardashians. “It’s disgusting,” Khloe said on the episode. “I’ll never understand the depths of this … I was just hoping for a better outcome for my daughter and for myself.”
Kim Kardashian and Kourtney Kardashian both responded to the KUWTK episode on social media, with Kim writing that she wishes "it could have aired sooner."
Of course, it’s great if Khloe is managing to co-parent with Tristan for the sake of her daughter, but are the public Instagrams necessary? We say no. Go with a good old text - if you must, Tristan.
