L.A. Lakers star rookie D'Angelo Russell is not keeping up with the Kardashians -- or banging one of them -- with sources telling TMZ Sports he and Kendall Jenner are just friends.
Rumors have been swirling that the two are in the early stages of a relationship ... which is why she was courtside at the Lakers game on Sunday.
But multiple sources (really good sources) tell us it just ain't true ... "They're not dating."
One source connected to the situation put it this way -- "Kendall is not into him."
We're told she was at the game because she's friends with one of the Dallas Mavericks players and his girlfriend.
Another source tells us, "They're friends, but that's about it."
Then again, that's kinda how it starts ... right?
