NBA player Brandon Jennings introduced Khloe and Tristan in September 2016.
"Brandon Jennings, who’s a basketball player, he’s a friend of mine and Malika Haqq’s, and he was like, 'You’re such a good girl, I want to introduce you to someone,'" Khloe told Ryan Seacrest during the Keeping Up With the Kardashians 10th Anniversary special.

So, I had a bunch of people and he brought him and we just connected."
