Tristan Thompson and Khloe Kardashian have their differences, but something clearly binds them ... their daughter, True.
Tristan posted this video of 4-year-old True, dancing up a storm in a kitchen. It's unclear if this was shot in Tristan or Khloe's house, but either way ... pretty cute.
They're dancing to "There's Nothing Holdin' Me Back." Watch ... True shows off her vocals!
It's unclear what the child custody arrangement is ... but clearly Tristan was able to spend some holiday time with his daughter.
Our sources say Tristan and Khloe are getting along ... despite the fact she learned he had gotten another woman pregnant while lobbying her to go for a second child via surrogate -- which they did.
And, speaking of that other woman, as we reported, Maralee Nichols and Tristan settled their bitter custody case ... he's paying her $9,500 a month in child support.
