In October, Khloe flew to Ohio to visit Tristan and watch him play at his NBA games.
Weeks later, a source told E! News that they two were “Exclusive.”
“She’s even gotten close with a few of his friends and they all hang out sometimes. Khloe hasn’t had this much fun with someone in a while.”
Khloe told Jimmy Kimmel in November that she flies to Cleveland “Very often” and enjoys “Being a little more under the radar” and traveling around without paparazzi following her.
Tristan is the third NBA player Khloe has been linked to romantically.
She and former Lakers star Lamar Odom finalized their divorce Saturday, seven years after they got married and following a more than three-year breakup.
Khloe also dated Houston Rockets shooting guard James Harden for about six months, until this past February.
