"No one with any kind of moral conscience cares about your sport victories. How you treat others says most about you. Shame on you @realtristan13"; "On to the next one really applies to you on and off the court doesn't it"; "There wasn't a single post about his son being born either".
Tristan did receive some positive comments, however, with some fans commenting: "All these comments are pretty bad. I am not going to post something to put you down. I wish you lots of luck. I pray for you and send balance your way so you can get threw the games and be a winner, and peace so that you can send love and calm thoughts to Khloe and the baby."
Earlier this month, Tristan was filmed kissing Blair in a nightclub before retreating with her to his room in the Four Seasons hotel, in Manhattan.
The incident took place just days before Khloe gave birth to their first child together, daughter True, and since the footage emerged, several more women have come forward to claim they have enjoyed dalliances with the NBA star whilst he was dating Khloe.
Whilst Khloe and Tristan have not commented on the claims, Kim Kardashian admitted on the Ellen DeGeneres show last week "I think everybody was heartbroken for [Khloe]. Literally days before she gives birth her boyfriend is seen on video cheating."
