Tristan's social media activity comes exactly one year after news broke that the NBA player allegedly cheated on his then-girlfriend Khloé Kardashian.
Earlier on Wednesday, Khloe, also took to social media encouraging her Twitter followers to “stay smiling.”
Also on her Instagram story, Khloe posted a photo of her and Thompson’s daughter True, who turns 1 on Friday.
The first cheating scandal took place just two days before she gave birth to True, where Thompson was caught on video getting close and personal to an unidentified woman in a New York City.
While Tristan never publicly addressed the allegations, in the usual Kardashian style everything was spilled on Keeping Up with the Kardashians, with the reality star admitting the situation was “humiliating” and calling Thompson a “complete piece of s—.”
