Tristan Thompson apparently ignored Khloe at True’s birthday

Khloe Kardashian and Tristan Thompson

Tristan Thompson and Khloe Kardashian were both present at True’s birthday party, but it appears that the NBA baller lacked manners.

According to the new trailer for “Keeping Up With the Kardashians,” they didn’t even speak at the event, as Tristan totally ignored his baby’s mama.

Sister Kim can be seen while talking to Jonathan Cheban, her best friend, in the trailer:

“He doesn’t even speak to Khloe. Khloe invited you. Be f**king cordial.”

Everything happened all the way back in April, when Tristan Thompson and Khloe Kardashian were spotted together publicly for the first time since the cheating scandal involving Jordyn Woods.

Oh, well, it looks like there’s no signs of making up at all between these two…
